Just look at the DS people. it's not sold out everywhere like the wii is and it still sells around 120k a week in the americas alone. Even when they meet demand the wii could still be selling 120k a week in america and everywhere else.

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.
