im sorry but by the time an actual mainstream developer makes something like that kinect will be old news and just like the ps eye a tool that was fun for a while but has become rarely used or spoke of in thoery an indie dev could do it but the mainstream media just couldnt do it they dont mod and you would want to do advanced moves in the game right yes well then you need the wrist movement so i geuss an indie dev could do it well because they are not afraid to mod but it would never happen well at least through the mainstream developers treat the system as a casual system until they are proven wrong by a large number of indie devs or microsoft themselves in theory it could happen but the kinect wont evolve enough to make it before they drop the updates and it just goes into a long state of deterioration like the ps eye did until the move came out and in reality all the kinect is is a ps eye with the ability to look up or down slightly and has two camera lenses the programming makes it special if it evolves enough to make a game that awsome ill go and buy my own instead of borrowing my cousins i just dont think it will happen
