Hey WPM, just to let you know it does NOT support the GameCube at all:

And as for everyone else I don't understand the complaints I'm hearing again. Only reason people complained about the Wii was really the lack of HD Graphics like the 360 and PS3, and now that we finally got it, I'm still hearing stupid complaints? MAKE UP YOUR MINDS.
So far I'm actually quite impressed with the system with the games I've seen for it (All of which I'd expect straight from the 360 and PS3 instead). I can probably afford both the 3DS and Wii U, since I'm getting the former for Christmas this year and the latter for my High School graduation next year. I was originally planning on either a Laptop or 360 as my Graduation present, but after seeing the Wii U I've pretty much ditched every other possibility there since now I have the processing power I like on a Nintendo system, which because I can name so many more games for a Nintendo system that I'll play, the point of buying a 360 or PS3 now is void to me, and both are starting to feel meaningless.
