As for games, I think more likely what has been already mentioned... some kind of virtual reality... but then, what if you get shot? Do you imagine a game so realistic you could actually feel the pain of a gun shot? (I know it's stupid, just thought about that
)
As for now, there has not been really big jumps in game consoles... only better graphics and resolution, but not much else...... probably in a PS3 you'll be able to play a game with graphics just like the ones you see in a full motion video in games like Onimusha or FFX......
