Whoever said LBP will reach 10 million in sales is an idiot. The PS3's install base isn't anywhere close to big enough, to have a game like that. Heck SMG GOTY, a mario game, that was on wii's massive install base is still in the 7-8 million range, and it has legs something you don't see as much on PS3.
I don't think anything will EVER dethrone mario. Mario is nowhere near dead, anyone that played mario galaxy knows this, the game is excellent, with spot on gameplay, and incredible polish. Nintendo is already hard at work at a new galaxy for wii, and I assure it will be good.
Support good third party games on wii. Buy games like house of the dead overkill, de blob, madworld, the conduit and boom blox.
