I have EyeToy: Antigrav, it was fun when I played it as a kid
As for the video, while he didn't explicitly mention Kinect, it's obvious that it's being referenced.
I think that we really need to concentrate on regular motion controls for now since we can barely get those to work half the time to begin with. While I do want Kinect to succeed in some points (and the other half of me wants it to fail so that Microsoft will shut the hell up), it's probably best to work the kinks out of regular motion controls for now.
Though the Move, for as much flak as it's getting for being a "ripoff" of the Wii (which, in essence, it is), it is sort of an intermediate between the Wii and Kinect in that is has both a controller
and a camera, effectively doubling it's possibilities.
I for one can't wait to see what either of these controllers will put out. Maybe it'll be crap, maybe it'll be gold, but I'm always optimistic with new technologies.
