I'm not saying it doesn't make for something amazing, just that there is better technology than projection that will give better results along with consistency. The 3D viewer has this concept beat and I would be dissapointed if Microsoft kept persuing the route shown above.
The ability to look left and right and have a huge surround display is great, something very exciting. Toss in sixaxis and a motion camera onto a 3D personal viewer and not only do you have the ability to look left and right you can do so while moving, no need to center yourself towards your tv. That and the viewer engulfs your entire range of vision, that 750" view mixed with true 360° scope and a move sharpshooter, priceless experience*. With individual eye 3D, depth can not get any better. All that without looking over to spot that target next to your lamp. Sure you can end up stumbling in your living room, but with a warning system when you get out of range and the ability to forgo turning around entirely by using analog sticks, there shouldn't be too much worry. Besides you could always invest in a rotating chair.

Before the PS3 everyone was nice to me :(
