The VR market right now feels kind of like the 3D accelerator market in the '90s, before Direct3D really came into its own, hardware manufacturers were still half-assing OpenGL support, and lots of games were programmed against vendor-proprietary APIs like Glide.
Would be nice if people had actually learned from that and rallied around a standard API/middleware for VR to start with, rather than trying to "console-ize" VR with hardware-specific exclusives. Maybe Valve/SteamVR will end up being that middleware?
