Oculus claims that the point of the Facebook acquisition was that they'd have infinity money. As both Oculus and Facebook assert that there's a blank check there, one would hope they've already also heavily invested in a high-quality software library. If not, they need to quickly start doing so. They could start a developer program where devs qualify for free or discounted hardware. They could even start their own game studio. Most other gaming hardware manufacturers do have their own studios and release their own games for exactly the reason you stated (ensuring that there are killer apps on their platform). Oculus has got to put that Facebook money to work!
