Most likely will be firmware-level integration. Social media companies, and Facebook most of all, are about engagement, which means making it easy to use Facebook from every platform possible. Having your head inside an immersive virtual reality just put people too far from Facebook I'm guessing, so the new FB Oculus will have a stream from your newsfeed that the firmware kindly muxes into your display at all times. :)

Google does this same thing with Android and other pervasive Google platforms and services. Why is Google making a phone? So that you use Google services a lot more than you otherwise would, which gives them the opportunity not only to drive up their search and traffic numbers, but collect a lot of data that is useful in targeting advertisements.

I agree that it's hard to think of any product tie-in with FB's extant line that wouldn't be disgusting. The only safe way to think of it is as a portfolio piece -- Facebook just wants to be associated with the next revolutionary name in computer input technology. It's hard to believe that it is so innocuous, though, and Zuck seems to put that idea to bed in his announcement.
