Sounds pretty neat to me. Especially the facial recognition stuff. It could tell who all is in the room and have the settings adjusted accordingly. Maybe I like the volume a little louder than other people. Natal knows I am there and adjusts it to where the software knows I like it. As for gestures, that would be quite simple really. All they need is a gesture to activate the system. Perhaps a double click with your hand and the word 'on'. Sweeps and swipes. Dual hand gestures such as zooming, etc. The NXE is actually set up quite well for a gesture based system. If it is anything like controlling the ZuneHD UI, it will be quite fun as well.
