This seems like a well put together and logical rumor, but the glasses part seems crazy if true. I for one, think that if they came out with a feature like this and it wasn't part of EVERY console sold, then that is stupid. Any new feature or tool MUST be part of every console sold otherwise it will likely fail in the long run. Even Kinect, with its strong start, has fizzled and people generally don't care about it anymore due to lack of new content.
Aren't a good portion of current 360 console sales still from Kinect bundles?
