Valve’s VR device could be the first on the market, when they deliver this year and the others stay with their plans of 2016. And now, Valve starts shipping the first versions to developers and movie studios. Oculus did that a long time ago, they have already shipped DK2 some time ago. But Valve’s product seems to be closer to the end version, which is obviously the most important one and as I said they want to deliver first. Unfortunately I am not able to get a prototype but I will see what others will say about the test version of the Vive.
