That's not going to happen anytime soon. Especially for Bing which powers not only the search website but many other Windows infrastructure in the background. With the Surface, even if it doesn't make any money, it serves the purpose of showing OEMs what they could/should be doing (much like with Google Nexus devices). And Xbox... they will be holding on there for as long as the whole console industry can (same for PS4).

We are going to see all Microsoft stakeholders (from investors to employees to managers) try their hand at the new CEO. No surprise the first movers are some investors, they're greedy and in just for the money.
