That would be amazing, if MS announces VR we might get a VR revolution after all. It's the only platform without announcement yet, and Occulus said they don't care about consoles. It has to happen everywhere at the same time. so that third parties can make games cross-platform for PC, PS4, XB1.
I have doubts about kinect because lag is supposed to be the worst enemy of VR. All currently announced VR products have 240Hz to 1000Hz acquisition, and Kinect is 30Hz. If your hands move with a lag in the game compared to your brain (kinesthetic awareness), the brain will go "barf".
