It's of some comfort to me that it's not MS, Google, Valve or worst of all, Apple. These are companies used to hardware who are more likely to think that they know best. I hope the owner of Oculus VR realises that their best bet is to stay the hell out of the way and Facebook are IMHO the most likely to do that.
After sleeping on it, I agree completely with you.
Oculus had to sell to someone. Sony was coming to eat their lunch. Palmer reads and posts extensively at reddit. This was posted on March 20th, at reddit which he most likely saw:Reddit Sony Leak
Interestingly enough, Palmer has said that it took them 5 days of negotiations to do the deal with Facebook, which means the same day this was posted they began the process.
Why did Facebook want to buy Oculus? To ensure there was a PC VR option. Otherwise, Sony would have eaten everything, and VR as we know it would be console exclusive and in Sony's walled garden. Facebook would be left out in the cold since they would have pushed Playstation Plus. Why use Facebook when you can connect with all of your friends and see them on Sony's Farmville VR?
Facebook just saved PC VR, and their future. If you are a PC gamer, this is the only solution that I can think of that will see mainstream VR adoption for PCs. Who else could Oculus have sold to that could have competed with Sony? Apple? Microsoft? They would have all insisted on walled gardens for their hardware, just like Sony. The other two tech giants are Amazon (virtual storefronts? not required for the future of the company) and Google.
Ultimately, it probably came down to Google and Facebook as viable options. Google has invested in Augmented Reality instead of Virtual Reality, whereas Facebook needs it to stay relevant. Google just didnt need Oculus, whereas Facebook did.
