4 Million I think. I reckon it will be a solid start for Wii U but sales will be sluggish for a couple of months after till it get some more killer titles.

Less than 2 million, my guess...

Based of the recent reports that Gamestop and the likes are already selling out, then it will be Wii all over again, maybe even worse... So basically what Nintendo can ship, but I still say 3 millions.

More than 4m. The only thing stopping that from happening will be supply constraints. It's a Nintendo console launching with a 2D Mario title in Europe and the States and a 2D Mario title and Monster Hunter U at launch in Japan with a Monster Hunter U bundle to boot.

It's going to sell an absolute shitload.

3 to 4m easily

2,397,452

I think 3.5 to 4 million assuming no supply issues. I'd like it to do more and I think it would if Nintendo could ship that many, but I'll stick with that prediction for now.

2.8mill

with one two week of numbers to go, this looks to be the best prediction.

edit: opps, two weeks by the OPs stated time frame.  probably going to be even closer than first glance.

Who won here?
