I think the Vive will be and remain the winning option to start, Oculus have made a total hash of the PR like microsoft did with the X1 in the installed base we will likely have 2:1 ratio with oculus playing catch up. They have slightly better HMD ergonomics and display but their room scale support and motion controls are missing at launch.
Touch controllers will come in a 3 months maybe, but I think we will see very quickly that while people will be eagarly adding VR support into existing games there will be almost no new VR games that dont need touch, infuriating Oculus owners as they wait. Given that HTC motion hardware will already be in the wild developers will have a heads up on implementing HTC support over oculus
By the time touch comes the PSVR wont be all that far away, its hard to see someone who was not a PC enthusiast suddendly becoming one and switching to PC for VR, they saw their console as 'good enough' and will likely take their first steps in VR 'trying it out' on PSVR.
Take in point the fact that neither console can geniunely manage full 1080PC, graphical compromises have to be made on both to come to that number but rather than be annoyed at sony that they only get 80% of the experience they point at microsoft and say look we get 2% more of the experience than you. Before this ends we will see PS4 owners telling us PC VR is crap because PSVR gives them 120fps, there is so much fanboyism that they dont hold sony even to the things they were promised, like full backward compatibility via in home streaming, which is still not available, how long did it take to deliver the instant suspend feature, both sides have both physical games and digital purchases and I cant remember anything that the PS4 promised over the X1 actually coming to fruition. I'm picking on sony as the winner of that 'debate' MS made their missteps too.
Hence for me I think 12months down the line it'll look like
1) PSVR
2) HTC Vive
3) Oculus
But all of this, ALL of it.. will just be lighting the touchpaper on it for gen2. The world will see VR and the world will want it, just like the world wants 4K, however the world will also look at its wallet and decide to wait it becomes cheaper.
