Xbox 720

Whichever is the cheapest.

Call me a pessimist, but I dont expect the Wii U to sell more than 50mil, and I expect it to be a close second.

As for 2014, though, I expect it to be the Wii U, because that's the year I expect Nintendo to do a price cut and release their "heavy hitters."

1. No.

2. VGChartz numbers are never proof. Are you implying that we shouldn't make statements based on VGChartz numbers?

3. The 360 and PS3 also had bad starts. Fortunately, they were able to recover primarily due to longterm support from 3rd parties. Unfortunately for Nintendo, their consoles have never received good 3rd party support. So there's reason to believe the Wii U won't have as much longterm support as the PS360, which would disable its ability to recover from a poor start.

4. Not just this weeks, but its entire life so far. Specifically recent weeks though, especially in Europe.

This is a little early I think. I know WiiU has been out for two months and I'm not making predictions about it until March when I see more about its late 2013 lineup and post-xmas steady sales. Let alone any idea what the rest of next-gen will do given I only have best guesses at price and software lineup.

I mean, if a PS4/neXtBox come out at the same price as a WiiU, then core gaming perception alone will allow them to outsell WiiU. It would require WiiU having virtually the same library and at a $100 discount to allow it to convince the average core gamer that Nintendo had the better option. Just a fact of the stereotypical (read ignorant) beliefs surrounding Nintendo.

Smash might move some systems, but it won't save the system. It couldn't manage to save the Gamecube.
Mario Kart sold well on Wii but that was mostly because of that wheel. I don't see the sequel selling anywhere near 33million.

The wheel is an interesting thing to blame Mario Kart Wii's sales on. It doesn't begin to explain Mario Kart DS's 22+ million sales, or the fact that MK7 is tracking well ahead of DS. Maybe Mario Kart sales are dependant on the hardware sales of the console, and not the other way around. But it's clear that the series has grown a lot in popularity since the GCN days, and it's not hard to imagine the Wii U iteration selling over 20 million, bundled with a harmless piece of plastic or not.

Xbox 720 baby!!

It's possible, but it all depends on the Wii U sales.

Either way, I think Wii U will definitely take 2014, with Smash Bros, Zelda, probably Mario Kart, and who knows what else Nintendo has up their sleeves, plus Sony and Microsoft's consoles will be very new (likely in the same situation Wii U is in now). After that, it's fair game. 2015 on is up for grabs.
