This + a video of people playing 'Job Simulator' have me wanting to cancel my Oculus Rift preorder and get a Vive instead.
When I see interesting exclusives X on Vive, Y on Oculus and Z on Playstation VR, I won't buy all three platforms. I'll just say 'screw you all, I'll pass'.
When Oculus releases its Touch controllers (hopefully before the end of the year?) you might see Vive titles ported over to Rift. Movement in the other direction depends on what terms and conditions are in the contracts studios agreed to sign.
Also, moving your character with a controller or keyboard can be nauseating. This is why the best oculus games are going to be "cockpit simulators" or they're just going to have a"virtual screen". The vives ability to move yourself with your own legs keeps nausea in check.
