When I saw Avatar in 3D, I also thought that the same technology could be really immersive in video games. But I was thinking it would have to be way in the future, at least two console generations from now to be affordable. I think if the 3D quality was on par with Avatar it would be a huge advancement in video games, but I think if it comes out too quickly and all that be created is a cheap effect like when low budget tv shows try to do 3D it will be seen as too gimmicky (Virtual Boy) and not widely adapted.
