> until some other implementation will show up That's the situation, I think. Someone, perhaps OSVR since they have Valve's cooperation or maybe Valve themselves, will eventually take the next step. But the point is that OpenVR has no ties to Steam, only Steam's implementation of it does. The fact that SteamVR is currently the only implementation is not a minor detail, but unlike the situation with the Oculus SDK there is a viable path forward for open source VR with OpenVR. It's sort of like OpenGL if Mesa didn't exist yet: you wouldn't say the situation is no better than with DirectX. See for example: http://www.roadtovr.com/making-valves-openvr-truly-inclusive-for-vr-headsets/ http://www.roadtovr.com/making-valves-openvr-truly-inclusive... The article may be a bit dated, since it was written July 2015, but I'm not sure anyone has written a more up-to-date summary.
