It will stay a year, the PS4 sells less than X360 did in Japan, it flopped.

I got mixed up. What I meant was that PS4 will never pass Wii U in Japan.

except is just what you think. I'm a gamer since SNES days and the only thing we know is: PS4 will be number WW. In Japan? Probably not. 

People please, be reasonable.
I don't have to point out the the issue with making 3 - 4+ year predictions based on 3 months.
It's simply way to early to call.
Exercise cautious optimism/skepticism, don't make unreasonable absolute claims.
Surely, you see the flaw in denouncing system sellers on the competitors platform, and simultaneously setting unrealistic expectations for the system sellers on your own.
Why downplay the competition, instead of support your preference. Why does one have to be a flop for the other to be successful?

It's not what i think, it's sales and common sense.
Wii U sells less than GC.

PS4 sells lke PS3 and as soon as it gets multiplatform, it wll be exactly the same, thinking otherwise is just delusionnal.

At this point of time, i think your "thinking otherwise is just delusional" comment is premature. Im not saying anything like WiiU>PS4 in japan or anything (cuz imo i think 2016/2017 it should surpass it), but your already claiming WiiU will be less than the GCN because of how its trending right? Then why not the PS4 to PS3 as well?

Isnt it maybe too early to tell on WiiU as well? (not saying it'll guarantee to sell very well, but maybe surpass the GCN, or get close)

PS4 has just started but looking at overall weekly sales it doesn't look too well overall. Vita might not have the big AAA games there but it has amazing support and yet its not selling Gangbusters and its not close to the 3DS which barely had anything these past 5 months (and there big games are coming this summer+fall).

PS4 will no doubt have the ps3 third party support but imo i think some people are overestimating ps4. PS3 will be 10mil when its discontinued (about 9.5mil as of now), PS4 doesn't look to be as big, Yes PS4 willl dominate WW, but i think last gen is something that wont ever (at least in the near future) be repeating again. 

I'll say PS4 depending how it pans out in japan can do Minimum 4mil + Maximum 8mil

I dont say WiiU will do less than GC ( will depend of the lifetime),  i say  it will be in the same order, 4-5M.

Whereas with all the big multiplatforms , it will be like several Mario Kart( and obviously exclusives), 4M is terribly pessimistic, it would need a very short lifetime, 7-8M would be the expected minimum.

delusionnal is thinking PS4 will sell like PS3. Everything dropped in Japan, even handhelds. But at this point Wii U will stay above PS4. 

Does it really matter? Wii U can stay ahead for the whole generation if he want to, the difference on a weekly basis won't be significant. Sales in Japan won't make anything for it on a global scale. How many of the same thread are we going to have?

I'm curious what your stace would be like after the holiday season.
