I've heard they would like to use Kinect to allow a visual chat when people play games. Skype would make since for this.
Kinect uses a (mostly) fix camera over a while area, and will crop the other areas out. It is actually a rather cool feature. It will track you as you move around using Video Kinect. It could follow someone's face and either show the face or an animated Icon of the person. It is an extra level of interactivity.
Then say, if you are in a group - when you speak your picture could come up and talk when you talk. Sort of how Group Chat works in Google+. I can see how it would help learn who people are - you would see them.
Although I hope we can be icons too- like in Avatar Kinect - cause I'm sure some people game in their underwear and I think that is not something I need to see.
