Its launches in late november in EU. No way they are shipping more then 3m systems for the holiday.

I think it will pass Wii U next fall.

Anyone who thinks the PS4 can outsell the Wii U numbers since launch do not understand that it takes time to manufacture the consoles. Is it really at all realistic to have over 4,000,000 copies available from launch until the end of the year? No, it isn't. The Wii U at the minimum will do 4m, but is 99.999% guaranteed to do more. This is why the question here is dumb and anyone who isn't delusional would say no, regardless of where their allegiance is.

Not if Mario Kart, Smash Bros. and Zelda have anything to say about it.

Ok, some point in 2015 

regardless of stock, it wouldn't come close to reach wii u.

the mentioned time period is not relevant to predict the future wii u months.

If Wii U can sell 160K in three months with absolutely no game releases, then I don't see how it can't do much more than 1 million from now to the end of the holidays with major releases. Even if it does a bit worse than launch, it shouldn't be hard to sell over a million. 2-4 million seems more likely.

If the PS4 isn't supply constrained, they will clear 6 million by years end. If the WiiU surpasses that, it will be a minor miracle.

1) Wii U will be closer to 7m-8m by end of year.
2) 99.5% fact that Sony cannot have that many built by end of year.

100% fact that even if sony could manufacture that much, not even 50% of the stock would be sold.
