I understand the concerns about an always on camera and audio recording (even if I think your phone is probably a bigger danger in that regard), but I'm having a hard time envisioning what the actual danger would be for having a machine track my skeletal model. The issue with fingerprint scanning is (1) that you can build a fake finger to bypass authentication and (2) you leave your fingerprints everywhere.
At the moment, I don't really think anyone is building fake skeletons to hack my Xbox account. It might make for some creepy Minority Report-style advertising if Kinect cameras become ubiquitous and the data is uploaded to the cloud, but I don't think we're anywhere near that yet.
