What I mean by the future of gaming is just that in the past couple of years we've really been focused on motion sensing controllers. And while the wii-mote, the kinect and indeed this rig are flawed and have issues to fix eventually we will get there. And we'll get better at sensing the movments of the player, not simply tracking the remote.
Its something I'd be really excited to do. I love paintball, lazer tag and all that stuff but the problem is you often need more people than are around and they require you to travel somewhere, sometimes pretty far. If I could explore an arena from the comfort of my home, but still frag my friends living across the country.. That'd just be great. I think one day we'll get there. Although as you said, these controls would not work with all games, I'm not suggesting all games would have to be converted to this system by any means.
