Well I don't think Nintendo is going to sell their entire 4 million stock until 2007 or 2008. But I do hope that Nintendo sells one million units in 2 or 3 months. That'll definatly prove to the compitition they're a force to be reckon with. Hey, Sega did it in a record 90 days with the Dreamcast, why not Nintendo?
As for the PS3, I think it won't do very well. There isn't anything overwhelming about the PS3's launch games, while the Wii will have tLoZ:TP, Rayman Raving Rabbids(It's coming out for the Wii first as a launch title, then the game will be available for the other consoles.) Elebits, Red steel, Excite truck, Call of Duty 3, Wii Sports, Tramua Center: Second operation and a whole bunch more! Not to mention the games downloadable on the Virtual console.
I won't elaborate the $600 price tag, because everybody knows about that at this point.
