Will Microsoft offer free consoles?!

With this morning's news of Microsoft planning to release subsidized Kinect bundles for $99 plus $15/month with a 2 year agreement, I can't help but wonder what is next.

Other than the fact that Microsoft wants a Kinect in every home, what is stopping them from offering a free Xbox 360 Slim without Kinect on a two year contract? It would be a game changer, and the consoles would sell like hotcakes.
