Facebook acquire Oculus Rift

I've been really excited about the return of VR since the hugely successful Oculus Rift Kickstarter campaign a couple of years ago. With each titbit of news my excitement has only grown, and I plan on getting one as soon as it's released. It's something I want to specialise in developing for in my third year at college as I really believe it's the future of gaming, and should open new design and marketplace opportunities. I guess I'm not the only one with today's announcement that Facebook have purchased Oculus for $2 billion. As much as I'm not a fan of Facebook I'm happy that Oculus now has a huge company behind it, the future of VR is pretty much assured now. However I do feel sorry for the initial investors, they invested in something that they felt part of, something that would grow organically and be championed by enthusiasts and then maybe becoming mainstream. I worry that if not handled properly the return of VR may be a flash in the pan like 3D, and if these big companies don't see an immediate return on investment VR will be considered a failure to be shelved again for the next few decades.
