Hmmm, I am not fully sure what you're trying to say. Are you saying Natal isn't responsive? I can't comment on whether or not it is, but there is no reason why it would be. A reporter had the chance to play Burnout using the Natal controls and he said it felt very smooth and he didn't notice any input lag.
EDIT: And on that note, I am going to bed. I'll check back in the morning but I suspect that this thread will probably be swarming with people posting comments that are less than intelligent.
No, it is resposive, but there is no way to deliver feedback to the players except from the audio and video, that's less output to the player than rumble feature and pressure sensitive buttons (like triggers). Unless another device is included and in that sense it will be somilat ro Sony's concept
Ah, now I understand what you mean. And yea, I agree, I imagine some things would feel pretty shallow. If you're using your finger as a gun and have to flick it back to shoot, I can imagine that being enough feedback. However, just holding on to a fake wheel would probably feel a bit too fake for my taste. Honestly, I am more excited about the technology and the cool little tech demoes than actually playing a game with this. I would love to whip out that drawing game when I am with friends and maybe navigate the menus with my hand, but I still prefer a normal controller.
If Microsoft really wants to blow people away, they should let you use your normal controller but add headtracking to the game. With a 3D camera, you wouldn't need anything else for 3D headtracking. That would blow away anything Sony and Nintendo have.
