Oculus Rift is probably the best thing going for 3D gaming in general, because adding support for that effectively adds support for regular 3D automatically.
On PC, any game rendered using a 3D engine can theoretically be played in stereoscopic 3D (especially on NVidia systems, since the effect is built directly into the drivers). The problem comes from in-game effects and shaders that often don't play nice with 3D, since they're built in layers and designed to always be rendered from just one camera. Adding a second camera in games like that can yield some pretty crazy results. There are folks out there (like Helix) that go to lengths to make games work well in 3D, but it's not perfect, and it doesn't work for everything. But, by adding Oculus support, the game will have to have the ability to render any scene from two distinct cameras, and render those frames fully rather than reprojecting. That will hold true for PC and console. Hopefully, the developers will see the sense of that and include normal 3D modes alongside support for Oculus.
