Because Wiimote and nunchuck're seperate from Wii itself ,much like an accessories.So there're still have many ways to improve its abilities ,or even it designed.
So ,if game's developers already see Wii sales going quite well now ,and know(as we know) that this console still need more hardcore games.
Then why don't they make some (good)hardcore games for Wii?We're still in the very beginning of this generation ,it maybe too fast to say who'll win and who'll lose. Same as how long this motion control'll bring Wii to.
