When Will Xbox One Outsell Wii U?

[Mummelmann]

Late 2014 probably. I believe both will get a price cut in Q4 this year.

Multiplats are a lot bigger deal on the One, it has a couple of exclusives coming as well and Live is a big deal since the 7th gen.
Smash and Mario Kart will be big, Yoshi, X, Hyrule and Bayo 2 won't do much at all though, I don't understand why people keep listing these games. Especially Bayo 2; this won't even be a blip on the radar on sales lists, it wasn't even very big on PS3 and 360, the only ripples it will cause are the wrinkles on the forehead of those who expect it to have any kind of impact on the overall hardware sales situation. X and Hyrule are fairly safe best for Japan, but Japan is a tiny region for home consoles now and then one big territory that matters the least for the global total today. Yoshi? What the hell? Even the biggest one on the DS managed 2.7 million and this franchise has been more or less irrelevant since the N64's days, this won't put a dent in anyone's armor, only add more wrinkles to the forehead.

Call of Duty, Assassin' Creed, Titanfall, Halo, Destiny, Final Fantasy, FIFA, NBA, Madden, Watchdogs, these are games that will certainly help the One in 2014, while we know that multiplats help the Wii U only marginally (Assassins' Creed 4 sold terribly on Wii U, same with Call of Duty), these are fairly big, or even giant games on the One. Mario Kart and Smash will be huge, no doubt, but they can't bear the brunt of the work alone and be expected to keep the Wii U ahead for long.

To those saying "never"; come on. It's inevitable, the only question is the time frame. October or November 2014 is my guess. Depends a little on release schedules, timing of price cuts, marketing and whether or not MS wisen up and make the Kinect optional.
