There was a thread about this not long ago that you should check out:

As a roboticist I am extremely excited by the Kinect - it finally has broken down the cost barrier to (reasonably) high resolution and fidelity ranging, as the videos that we are starting to see on YouTube with quad rotoros and the like are starting to show.
As a FIRSTer, I doubt that we'll see a Kinect on a robot this year (there is a nontrivial interfacing problem that needs to be solved - probably by using a separate onboard PC that meets cost and power rules - before we can use them with the cRIO). Moreover, there haven't been a lot of FRC games where I could think of high value uses for a Kinect. But I hope someone does it, and I hope it ends up being as cool as I would imagine!
