Microsoft has announced a new VR partnership with Valve at E3 2015. It revealed the news at its big Xbox conference, where we were also treated to details of new Xbox games such as Gears of War 4 and Rise of the Tomb Raider. Microsoft also demoed Minecraft on its HoloLens AR headset.

What the partnership means for PC gamers looking forward to Valve and HTC's Vive headset is anyone's guess at this stage. We weren't given any more details than that the partnership exists.
Oculus announced a similar Windows 10 partnership with Microsoft at its big pre-E3 event in San Francisco last week. An Xbox One controller will be bundled in with each Oculus Rift headset and regular Xbox One games can be streamed to a virtual Oculus theater in VR.
It does leave Sony, Project Morpheus and the PS4 out in the cold somewhat, though as Microsoft is now involved with two of the big three high end VR headsets due to launch properly in the next 12 months or so. This also lends weight to the theory that with HoloLens in the works and these high profile partnerships, the Xbox VR headset is simply a tech myth.
Microsoft said that it would be "working with Valve to make Windows 10 the best platform for VR gaming" - stay tuned to Wareable for more details on what this means this week at E3 and as we gear up for the HTC Vive's consumer launch by the end of 2015.
