So now Sony will need to prove themselves to get support??? Those 3rd parties prejudice and bias.

Well, whoever expected it, got it wrong.

Difference this time is that Switch is in same type handheld, and that Switch actually has modern tech/architecture, has support for all modern engines and closer power gap to competition, those things make huge differences for japanese devs.

I think it's more you think you have right to not have someone respond to you tbh and it's contributing to you failing to even read what is being said to you because if you read properly you'd know that that I'm pulling you on using vague similarities to push an argument in saying two different games can have the same appeal so your dictionary part and all that is not only null and void you've literally thrown in a response to your own failure to understand the replies I'm not sure if you don't understand what vague similarities means or if you're just skim reading the posts.

You're free to think what you want just as I'm free to think you're one of these people who thinks they can post something and not have it responded to I'll say the same thing to you as I do to others who get ruffled, this is a forum if you don't like someone replying to you don't post, notice how your only response is about preferred platforms when not one part of any of this debate was about wanting it on any platforms or even comparing platforms that's a sign on your part of your defensiveness ironically a sign of ego as well, I don't sugar coat things and won't for you either don't like it don't respond I'm having a discussion with you but doesn't mean I'll baby you in replies that's how debates are, someone else even highlighted my point as well in how they found out the game was drastically different from what appealed to them and what further backs my stance is the historical performance of the series in the west.

No the problem isn't that I assume you don't know how grinding works the problem is that you're overestimating the potential appeal and using vague examples to try and build a case at which point I point out the flaw, BB and DS have grinding but non on the scale of MH and I've already highlighted that similarities in HZD are vague at best.

True MH3rd didn't come to the west but then Tri and the PS2 games did every non portable version has failed to take off even though Tri did better than usual but then even on portable the sales in the west are still only luke warm as well.

No, I am happy to admit mistakes but I don’t know if I can say the same thing for you. I want a healthy discussion but problem with you is you love to cherry pick examples to suit your arguments. For example using games like Monster Hunter Frontier, MH3rd PS3 and the first two MH on the PS2, MH WIiU.

PS2 yes the install base is larger but you are forgetting that not all PS2 has a built-in network adapter. MH is not a popular series before as well. You should know it better than me.

Monster hunter frontier is an MMO.

PS3 MH is Japan only. Its irrelevant with our discussion about the west? Also not considering that it is a port of PSP MH portable 3rd.

WiiU MH- WiiU failed no more explanation needed.

The only comparable MH games is from Wii and to some extent 3DS.

Wii fanbase are erratic. Mostly consist of owners that loves Wii Sports or casual games. There's not a lot of heavily multiplayer games.

3DS more popular in Japan. PS4 and XBO more popular in the west. Do I need to explain more?

3DS closed area, PS2 Graphics.

MHW Open areas, seamless, HD GFX. With the information that we know so far it’s a great leap from the previous MH

We still don't have a proper metrics for MH in the west because this is the first time an MH that is build from the ground for home console and in the west in mind.

My understanding from the word vague is unclear and indefinite. HZD has a clear similarities with MHW. I know HZD and MHW are not comparable because they are two different games and they are not the same but to ignore they have something similar is a different matter. You are acting I cannot use that as an example because in your own definition they are not similar. Why HZD cannot have the appeal of monster hunter when Monster Hunter does it best? What stopping Horizon Zero Dawn owners from liking the game? You still haven't explained that clearly. I already provided explanations why they are similar it's your time explaining why they don't share a similarities at all or or why you think it's vague similarities.

The same can be said with Soulsbourne fans. What stopping Soulsbourne fans from liking the game? Both will test your patience, both have the same combat style. The difference is most of the time you will play with your friends in MHW so the insane grind you are talking about can be potentially off set with playing with friends.  

No dude you gave the examples I highlighted the flaw in them, I used examples of games in the very series itself to make a point you're picking random games with vague similarities to try and build a case. The two previous console MH games have come and failed to make a statement, the Wii fanbase is erratic in your view yet as a console user base they're so far the ones who took the most liking to MH.

Do you know what the highest selling MH game is? Freedom Unite which was released back during the PS2 to PS3 era this debunks the notion that the franchise is more popular now than before it's maintained it's popularity for over a decade now, graphical leap isn't going mask the specialised taste required to enjoy MH.

You finally start to realise the point where you say HZD and MH aren't comparable as games with the similarities, that's the whole point many games have vague similarities in their concepts but because they aren't comparable the appeal don't not carry over you answered your own question in you post here. HZD is a wide open world adventure where you follow the story and side quests MH is a mission based progression game with a tonne of grinding required for each mission. Even the open world aspect in MHW is not like HZD as it's more like MGSV where non of the areas are seamlessly connected you just have large areas specific to the mission, the structure of MH  along with the application of its mechanics are vastly different from HZD, Soulsbourne and all.

The irony is that it's far easier for MH fans to get into these games than vice versa.

1st 

Wii MH: main series released wordlwide
PS3 MH: port from the Monster Hunter portable 3rd. Japan only.
PS2: (The original games for the PS2 required a monthly ¥900 (US$10.19). Not all PS2 has a built in network adapter.
See the flawed comparison here?

The highest selling MH is portable 3rd in Japan.

Monster Hunter Freedom 3

• Release : Dec 2010
• Platform : PSP, DL
• Units : 4.9 million units
  Japan only
  
  

MonHun started became popular because Portable 2nd.

Did wee see another PS2 installment after 2? Which was released before Portable 2nd?
As for PS3 MH. It was cancelled. The only MH it have are MH frontier (MMO) and the port (Japan only). 

Are we going to  still continue about the unfair comparison?

3rd
Thank you for that explanation.
No, I am not admitting that they are not comparable because of the similarities. I am only saying they are not the same game. 
Your point is they have a vague similarities. There is a clear similarities between HZD and MHW. 
Anyway, my real point was the PS4 audience is diverse. I cited that two as an example. Especially HZD. For me HZD is Monster Hunter Light. In terms of the Hunting aspect. Take it as you will.

At the bold Capcom already made some changes for that to cater to the west.

Tokuda: “We do have the same sort of Low Rank, High Rank structure, but in the older titles when you go to High Rank, the story was no longer a concern, but this time we want to make sure the story continues on a thread throughout High Rank. One big difference in the structure is that there’s no longer a separation between village hall and gathering hall quests—that distinction doesn’t exist anymore. You get a quest and you can choose whether to play it solo or online.”

Ryozo: “I think we’ve made a nice, meaty story for you guys and as mentioned, it’s something that carries throughout the entire game, so it should be a lot of fun.

The game will feature a story mode offered through the quest system. Unlike previous games, where the story mode led the player through and to complete the "Low Rank" quests, before opening the game to more difficult "High Rank" quests without a story driver, World will have a narrative that continues into the "High Rank" quests.^[13] Instead of quests that required players to slay a number of smaller monsters or collect resources, World will offer these as Bounties or Investigations that can be achieved alongside the main quests.

One last point. 
You cannot deny that MHW is a great leap from the previous MH. Call it overestimating or whatever you want but from the information we have so far in MHW. I can see it succeeding.
And this a first true MH that PS4 will have after all these year being a Nintendo Exclusive. This is also the first main MH that is multi plat. 

No flaw in the Wii game so the point pretty much stands it was even marketed heavily and publish by Nintendo themselves, also the highest selling MH game is Unite with 5.5m sales I don't know why you're only bringing up sales in Japan for the series, MH became popular with Portable/Freedom and grew from there with it reaching its high point with Unite don't get the whole unfair comparison because this is looking at games in the actual series and even on Portable and Wii it didn't take off.

You're not reading the post properly you admitted they're not the same game despite having similarities this is the whole point if they're not the same type of game you can't use one as a basis to work out appeal for the other, HZD is not even MH lite that in a way disrespects HZD some what its its own take on a familiar concept. The changes may in theory help but in practice it actually remains close to the previous games as the core structure remains, ironically Generations approach would have helped people get into the serie easier as it had significantly reduced grinding and faster progression.

The taste required to get into the game is too specific I don't see them emulating anything close to what they pull of on portables in Japan sadly, it could match the Wii version.

Just an observation. You loved to twist my words . You loved to nitpick examples to suit your argument. You loved to put words in my mouth. I never said they have the same appeal and will instantly buy the game. I never said HZD and MHW are the same game. 
Also, you keep on ignoring my main point up until now that PS4 crowds are diverse and I only cited BB and HZD as an example. Which is saddening.

Let me start with Horizon Zero Dawn.
Yes, I admit they are different because I never claimed they are the same. What I said is there is a similarities which up until now you refuse to acknowledge. I even cited the developers telling us that HZD was influence by MH hence the similarities we are seeing. 

Let me use an analogy here. ( I really don't know if it is because English is not my native language or you are just plainly ignoring my points)
Person loves Strawberry Ice cream (Horizon Zero Dawn) and then he saw a Strawberry Cake (Monster Hunter World). Are they both the same, No, But do they share a similarities, yes. They have Strawberries. Since the guy loves Strawberry Ice cream there's a big chance he will try to eat the Strawberry cake. It's either he will like it or he don't. So my main point here is the guy tried it. 

If people who love HZD and loved the hunting aspect of the game. It's possible they will take a look at the game and potentially buy it. They will either hate it or love it. The funny part here aswell is I already cited the Developer of the game telling us that were inspired by MH hence the similarities you are seeing.

I hope this is very clear. I tried my best to make it as clear as possible. 

BloodBourne:
My initial point was you will need to grind in BB aswell. I know the difference between the two as I have already told you.
I tried my best explaining it you that you need patience in Grinding. Bloodbourne is a game that will test you patience. You still love to ignore the patience part but then again we can agree to disagree as I have already told you.
Also, I told you that Bloodbourne's combat style is a lot similar with MHW. With heavy and small attack, the Stamina and slow paced combat.
As I mentioned above. It's possible that they will try it but it's up to them if they will like it or not.

As for the Wii part.
I already told you that Wii is the most comparable of all the MH games you mentioned. My problem is with your other comparisons that you are using.

You used:
Monster Hunter Frontier: MMO
PS3 MH: A port of the PSP game and didn't release outside Japan.
PS2: Not all PS2 has built in netowrk adapter. Under a monthly fee in order to play the game.
WiiU MH: WiiU failed.

But even if we compare both Wii and PS4. WIi has a lot of Casual crowd as opposed to PS4. Majority of PS4 fanbase consists of X360 and PS3 users from the previous Gen. Unless you are telling us that Wii and PS4 shared the same fanbase?
