Not to mention, it's only 1 game... for this to work, pretty much 99% of AAA titles need to be designed for VR (not just the "enable VR" checkbox).
Call of Duty Black Ops III was just released... no VR support. Battlefront was just released, same thing. These are the AAA titles that would bring support... but they aren't. (it also shows Facebook et al did a terrible job of convincing AAA studios to think towards VR... which could be a nail in the VR coffin in they don't come around on their own).
(and yes, I know there are ways to get both games to work with VR... but it's not native, and the game wasn't designed with VR in mind).
Given it can take 1-2 years to develop a AAA title, it could be a long while before we see it becoming the "norm". In the meantime, all of Oculus' competitors will be on the market, probably cheaper and better (due to learning from the first-to-market's mistakes).
