hmm im still a little skeptical about how well it will work with hardcore games. I had an eyetoy on the ps2 and natal isn't much different from it.
I mean how do you play a game like Gears? You need a reload button, cover button, run button, aim button, zoom button etc
From a trailer I have seen and I do not know how authentic it is (the one with the family doing the car race and the dad changing the tire in the pits), it shows Natal can recognise certain gestures. If so, Natal maybe awesome and I can see some kick ass games being made, but even then, I don't see it being practical and there are still too many questions.
If it is, a Capcom game, I think it would be awesome if it was Final Fight, but lets face it, it would be an exhausting affair lol
