natal wont be used in es5. its cool tech, but the next ES will have no need for it, unless its something like facial construction. It wont happen, but if it did then that would maybe be cool.
As it was mentioned in http://www.gamesas.com/bgsforums/index.php?showtopic=1042112&st=0 (about http://gear.ign.com/articles/102/1027885p1.html) Bethesda is on the list of Natal developers and publishers. Unfortunately we don't have any details with this, it could even be for a game they're publishing rather than developing.
I heard that Project Natal is going to be a PC thing as well. But still, don't wanna screw over PS, unless TES is gonna become a microsoft only game. D:
That wouldn't surprise me, since the beginning one of the XBox's strengths has been its relative compatibility with the PC.
Also, your new avatar made me lol.
Thanks
