Thats jut an excuse wii haters often use cause its doing great. Same with its not next gen. I don't remember Nintendo saying that but maybe they did. But it's a videogame console like the 360 and PS3 and is competing with them.

Bet with OriGin: Within 1 year Super Smash Bros. Brawl will be ahead of Mario Kart Wii (when aligning the one whole year from each region). 2 week ban from Vgchartz for the loser. Edit: Darn! Looks like OriGin will win.
