I have a sneaky suspicion that Natal isn't remotely what it's cracked up to be. But I'll wait and see. Things from last years E3 with Natal were a bit odd, like the machine scanning a kids snowboard on the fly and then using the texture in the game.
I've got a wait and see attitude about everything at E3 lol. Especially with the baseless hype the consoles throw out each year. CG they 'claim' is actual gameplay, only later to reveal the truth, things like Natal with it's super capabilities that are probably very limited in reality, etc.
