PS4 will pass 100M that's a given! but i think it'll end up between 120 to 133M, mark it!

Sorry but no company is literally going to NOT support their own devices with software lol. I suspect the reason we didn't see any vita stuff at E3/Gamescom is due to Sony realizing that the ps4 needs to be a big hit RIGHT NOW because pretty much everything else Sony sells is doing horribly. Now that the ps4 is doing amazingsauce in console/game sales they can focus on showing off the vita games they have been keeping a lid on.

Really grasping at straws to support your unrealistic point.  

All of their devs even once that were mainly psp ones are in PS4 game production right now, they are using 3rd party smaller devs and indies types to suppport vita.  I dont suspect that, its a literal fact.

It seems most anti ps4 arguments are mostly hopes and dreams opinions and nothing more.  Facts and reality destroy em all the time.    

Playstation success is due to third party strong support with only first party Playstation 1 and 2 would sold that's much, 3rd party don't want to support handheld for somes reasons.

Sony don't own 3rd party studios so they can't force them to develop on psv.

People compare the PS4 to the Wii because they've been the consoles with the strongest launch periods out of each generation, and the PS4 is selling less than the Wii did.

I highly doubt the PS4 will crack 100 million unless this generation stretches on for 8-9 years. It's had a strong start, but when you compare all of the current-gen consoles to their last-gen predecessors at the same point in time, people aren't buying into this generation anywhere near as quickly as they did the last.

I did these calculations on another site about a month ago, though they're still fairly current:

PS4: 10m vs. PS3: 5m
One: 5m vs. 360: 5.5m
Wii U: 7m vs. Wii: 32m
Vita: 9m vs. PSP: 29m
3DS: 44.5-45m vs. DS: 55-60m

The PS4 is the only console tracking ahead of its direct predecessor right now. The XO and 3DS are tracking slightly behind, and the Wii U and Vita are tracking way behind. When you add everything together, it suggests people are either content with the consoles they bought last gen, or they've moved on to other devices like iPad, smart phones and even PC. The PS4 has also been riding a wave of insanely positive press whereas the PS3's reception was mostly mixed until a couple of years in; I suspect in a couple of years time, the PS4 won't be tracking so far ahead.

I think it's definitely possible that the PS4 will still go on to be this generation's best selling console (after the 3DS, anyway), but if so, I'd expect it to hit between 60-80 million. I don't think any console is likely to get much higher than that in this generation.

Wii sold even faster then ps2 and in the end ps2 still 50 millions ahead of wii so you're argument is not valid.

Both vita and wii u had a lot worse support then psp and wii that's why there's doing horrible and x1 is doing less then x360 because a lot of x360 owner bought a ps4 instead

PS4 is doing horrible in Japan compared to how PS3 did in Japan. All around I think PS4 will do great at least 80 million. Right now the PS4 is selling on hype alone. When the big hitters come out and support for PS3 drops a whole other wave of increasing sales will hit. A few reasons I can think of why PS4 may not get up to 100 million is due to the possibility of a shorter life, many gamers are leaving consoles and moving over to handhelds and even then many are becoming casuals and sticking to Candy Crap games. Also, the time and money it takes to get AAA games out on these systems is much higher which means more risk. Time of the indie has come. Even if PS4 doesn't get to 100 million it will do wonderful and likely will beat out Xbox1 and Wii U as well. 

I think the title wasn't supposed to match the OP.

Did you check the numbers and release date for both? First wait for holidays in japan this year, if ps4 is still selling bad then I'd agree

I agree. PS4 will do far more than 100m.
