People seem to be very limited in their vision. Regular games will not be going anywhere on the 360. Reach will still be a controller experience and will be kick ass. Natal is only something that is ADDING to the 360 consumer's experience. It isn't taking away anything. Not currently anyway. The only way it would take away from the regular controller experiences on the 360 is if it was incredibly successful. And if it becomes successful enough to alter development trends for the system, then that means people are wanting it. I truthfully do not understand the resentment towards the hardware. It will be there for people wanting it, and it will not be there for people who do not want it. Simple. Not sure why having more shit available to you is a bad thing.
If you would like to see some ideas for Natal(which, judging by my thread's post count, there aren't many interested in passing ideas around, only passing FUD) here is a thread with some ideas I had: http://www.vgchartz.com/forum/thread.php?id=90211&page=1
The hardware IS coming, perhaps it would be more fruitful to discuss what IS possible on the system. Why try to shoehorn current genres onto the system. Trying to play tennis with a baseball bat is not a good idea.
