Reasonable on 06 February 2012
Seems unlikely. They might have to eventually but right now that would bring them into huge conflict with Samsung, etc. and likely get the major electronics retailers to push back against them.
What I could imagine - somewhat like Mobile phones and their OS, is a Samsung TV with included MS console. Anything other than a partnership would put MS into a competition with HW vendors I doubt it would want.
Try to be reasonable... its easier than you think...
