What is the official word on Unity5.x, VR and OpenGL on Windows?

My current project requires a native plugin for rendering and then compositing our content into the VR eyes. This renderer requires OpenGL.

Since the Oculus 0.4.4 there hasn't been a working version that has supported OpenGL. It's coming up to a year away since that sdk release.

This is what I've found while testing different builds, runtimes and sdks today.


In the Unity5.2 patch notes it mentions "VR / Oculus Mac: No image to HMD. No workaround until 5.2.0p1"
Could I assume that this means OpenGL is being supported for Mac? Possible that there is a branch with OpenGL support?

Could I please get the official word about VR OpenGL support on Windows?
