So if people will use their body as a controller with Natal, what if they are missing an arm? What about kids in wheelchairs? Does this mean that only normal people will be able to play natal now? I heard that if you put your hand behind your back in Natal, it knows that is behind your back. If you have no arm then theoretically it would believe that your arm is behind your back. I can foresee many problems with Natal and handicapped people in the future.
