Facebook has a decent track record with most of its purchases and doesn't tend to push anything on its company buyouts (Instagram, Whatsapp). I don't think Facebook will mess with the current path that the Oculus team intends to go with which is precisely the reason that they were chosen as the optimal company for a buyout. It's really no surprise that they took the buyout considering Sony announced project morpheus which introduces real competition to the equation. The Oculus Rift can not realistically compete based on scraps. Sony is a powerhouse and has quite a bit of money to put behind bringing their version of virtual reality to market. I'm quite excited to see some big companies put their money behind virtual reality. This is the beginning of a new entertainment industry and it's quite an exciting time to be alive to see it unfold.
