Xbox 360 camera eyes EyeToy?

Will the Xbox 360 camera have tracking abiities similar to the Sony EyeToy and motion-sensitive Revolution controller? German blogger Erzengel360 dug up a recently updated Microsoft patent for "relative range camera calibration" that would seem to support the notion. Of course the PR cogs at MS told him the details of Project "Vision" will become clear at a later time.

I assume nobody is going to complain about added functionality, especially if it allows you to flap your arms at a glorified webcam. What are your expectations for the 360 camera?
