I think this is going to be awesome!
I still haven't heard a clear explanation on what is needed for games to support this.
Is there a separate API? Are games that already support 3D in some fashion compatible?
I see this being great technology IF, and ONLY if it can be used either via an adaptive plugin or API with any game.
If a game has to be developed around the Oculus hardware, I see this as an uphill battle.
AFAIK, there is an API for this, and it is very easy to implement. Basically you need 2 view matrices instead of 1, and tie their rotation around a point in between them, and then rotate according to what the Rift tells you. Of course you need to render to both eyes, making it quite demanding, but you can also skip things like anti-aliasing, as it shouldn't be very noticeable with VR (your brain will filter the separate images anyways, reducing aliasing).
So yes, it can be used with any 3D game, which adds support.
edit: turns out there is a bit more to it, but still doesn't seem too difficult: http://gamasutra.com/blogs/NickWhiting/20130611/194007/Integrating_the_Oculus_Rift_into_Unreal_Engine_4.php
