Games using holograms?

Apparently Rare decided to commit itself on predictions of what will be the evolution of the game in a few years.

Scott Henson (boss of Rare) stated bluntly that the future of videogames are holograms.

You already have figured out just fine…. holograms, which until a few years ago seems to be a mere utopia and that still has not been properly developed as technology.

Henson foresee an increasing amount of sensors and each type of sensor with a specific task, of course, each different from the others, so to perfectly recreate ourselves in 3D version in the form of a hologram.

According to Rare Kinect for Xbox360 is only the first step in what will be the real evolution even though at the same time admits that it will take several years before to get there, but it certainly will.

Play and see myself in holographic form? Uhm... at this point I go to the mirror and I look stupid doing that.

According to you a hologram-based game (and don't plan to have the entire room turn into a hologram, but only few items and yourself) would be handy? It would be nice? It would be useful?
