Everyone with a wii should check out this game. It just came out in japan on the 22nd but the whole game is in english.
I have played the game for about 40 minutes right now so i cant say the game is perfect but sure the hell is fun and intriguing.
Here are some links....

It won a lot of awards at E3 - I didn't know it was on Wii though :) I'll see which is cheaper, Wii or XBLA for this one. Everything XBLA is overpriced deliberately.
[EDIT] - Dammit, I'm thinking of Limbo, but Lost in Shadow is reportedly coming to XBLA + PSN as well, so I'll wait :)
