ArsTechnica is reporting that they have a source who is telling them that a major publisher currently planning to release a new virtual reality game on the Xbox One in 2017 and that game will be shown at e3. This is a pretty big report. Unless MS is branding an Oculus (they  have a previous relationship with Oculus) this can only really mean that the previous reports of an Xbox VR are probably accurate. here is the exact quote from the Ars article
“Ars can confirm that at least one major developer is currently planning to release a new virtual reality game on the Xbox One in 2017 and plans to show that game at E3. The news lends credence to multiple recent reports suggesting Microsoft is planning a more powerful, VR-compatible Xbox One for 2017. The information was provided to Ars directly by the developer as part of pre-E3 planning and was confirmed by a PR representative.”

So that seems pretty definitive. Ars goes on to say that its a well known European Developer and that the game is in an established franchise with a lot of other fanct stuff that basically means nothing at this point. Brokenjoysticks will be live at the Xbox press conference on June 16th to bring you any news about this new device, and Microsoft willing our first hands on impressions. The game is supposedly going to release on PS4 and PC as well, so I guess we can expect to see it coming to the Rift and other VR headsets as well.

Microsoft has yet to officially announce anything VR related, and Ars is very instant that this title has VR in the name, so they may have just blown the whole VR cover off of MS.  With only two weeks left till E3 its a toss up when a rumor comes out like this one. Its probably true (reliable source, close to reveal) but as always with rumors take this with a large grain of salt, it could all just be a false flag for something else.  Neogaff also has some compelling evidence, the listing of several VR categories for companies that develop for Xbox.
