Wii Fit will outsell Grand Theft Auto IV this year. Yeah, you read right: the latest entry into what is arguably the biggest hardcore video game franchise around is gonna get whooped by an exercise tool -- we're not shocked, we're just laughing. GTA4 was dominating at first, but with time interest has waned while Wii Fit and its included Balance Board peripheral have stayed hot despite supply shortages. Nintendo's hardware-focused strategy seems to be working; the Balance Board install base is approaching 12 million, or roughly 30% of all Wii owners. You can bet it'll be put to good use in future games and other, less mainstream applications even after folks have given up on losing weight and resigned themselves once more to lifelong loneliness.
