GDC: Mario Kart Wii playtests hit web
Both Gamespot and IGN have posted extensive playtests of Mario Kart Wii today, so if you're up for ploughing through about 20,000 words on a Nintendo racer, you're in luck. Gamespot got very excited about the whole thing, saying it was "pleased" with the game. There's no solid release date from either site other than "later this year".
