1) Facebook could stay hands off, giving the company the company the breathing room and capital to absolutely revolutionize gaming, and then on to other fields.
2) Oculus as a "communication platform" is attempted too soon and the core team is drawn away working on pet projects resulting in a drastic lack of focus, which would kill the product (momentum is key here).
Given that Facebook is the acquirer, I'd lean much further towards #1. If it were Google, I'd bet money on #2 (see the GAE thread today).
I don't think the privacy stuff is going to be a big deal, by the time this turns from being an interface device to an integrated product like Glass, the market will have matured and there'll be plenty of competitors offering the former.
So, it'll either good or bad. You read it here first, folks.
