I think out of the three major vr products, oculus rift has the best chances to succeed. First it is backed by Microsoft in combination with Facebook. This is basically unmatched. And it will get easy support from Windows 10.
Valve is new to the hardware business (HTC is not), they will have a hard time to sell those steam machines and I just don't get why they are skipping such a crucial E3 for them. Sure Steam is big, but I bet PC games will support Oculus as well.
Morpheus... Well that is Sony doing their own thing, without a major partner and no relation to PC gaming. Somehow this sounds more like HD-DVD than the other products.
I agree though HoloLens will be a new level.
Imagine not having GamePass on your console...
