Pokken dosent count because thats a Pokemon company/Nintendo decision to bring it over, rather than Namco.Outside of that, some are ports of years old games, others are really old games that should have been part of VC and there are games like Xenoverse 2 and MH XX that not only are one year old(with MH XX being port of a port), but having better sequels and/or versions comming up, making those games kinda pointless.

I will give you that Capcom and Bandai didnt really anything worthwhile in the first year for PS4 or XOne, but then again, I dont remember them having something to release back at that time(they didnt have a game being released that year for other platforms as far as I remember, so you cant release what you dont have), much differently of what is happening now.So your comparison is kinda a moot point.

Playstation gets the benefit of the doubt because every Playstation console has sold over 85 million units and a PS4 game is also easily trasferrable to the XBox One and PC platforms, the chances of all three of those formats "failing" is virtually impossible. Also the PS/XBox ecosystem are largely driven by third party software sales, so third parties will naturally gravitate there. 

Many of us knew this would happen and we are not experts, how is possible they weren't able to see it? It was obvious for anyone with a brain.

The Japanese third party companies have  lost faith in the console market. That has nothing to do with Sony or Nintendo. The last Hitman was being developed as a  Pc only MMO and, if it wasn't for the success of the PS4, they wouldn't change the game.  I don't know why, but those companies need to be 100% sure, before the development starts,  that the game will be a success .

“Obvious” for those who were already sold on it because it’s from Nintendo.

Everywhere else, people were unsure about it because of how far behind the other consoles it is from a power perspective. Meaning porting any existing and upcoming projects wasn’t going to be a smooth and straight forward process. Plus, coming off the failure that was the Wii U, nobody can hold it against them for being cautious.

Also, I would suggest you keep those ironic jabs about people’s brains out of your over-defensive comments if you wish to stick around. 

No, this has nothing to do with "because its Nintendo" bullshit, WiiU was form Nintendo and I never ever thought it would be a big hit, however it was obvious that Switch was going to smash Japan market, it had all the ingredients for that, in order to not see that they need either a huge lack of vision or a huge lack of brain.

What kept 3DS selling after Mario 3D Land/Kart 7 released in its first holiday?

Alot of people are acting like Nintendo has blown their load already and will have barely anything for 2018 which is odd since Nintendo has dozens of million selling IP that have yet to be released.

It was a handheld, it was always going to be a success. It was also obvious it was going to be a bigger success than the 3DS because Nintendo could now focus entirely on one platform instead of splitting their resources between two platforms. 

Nintendo has a 100% success rate when it comes to handhelds so far, so if a Japanese gaming company didn't see this coming then they deserve to fail. The ones who were too late to react or bet on the wrong horse have pretty much sealed their faith (Capcom, Level-5).

Was the Wii U being a failure part of Nintendo's plan?

Everyone in this thread is being quite ridiculous. These big developers who just so happen to be Japanese aren't looking to be selling their games in only Japanese markets. Of course they'll be cautious of a system, even if it's portable. Get your head out of your ass. It's so easy to say this shit after the fact.
