Will VR be a platform in itself, or will each individual HMD be it's own separate platform? I pray that the former is true.
Addendum question for devs - how hard is it to port a non-VR game to VR? Does it require a top to bottom overhaul? Imagine games like Rise of the Tomb Raider & The Witcher 3 - imagine those worlds in VR. 😮
Some will, some won't. It will be just like the current console market, although with a PC you will undoubtedly be able to find some work-a-rounds to get something working that might not be supported.
Rest assured that Steam will support as many HMD's as possible (definitely the big two).
