To sum-up my speculation – I believe Xbox VR will be created in-house and in partnership with AMD. I can almost guarantee it will be wireless. VR titles will be exempt from the parity clause between Xbox One and Project Scorpio as the VR headset will only be available on the latter due to power constraints. Fallout 4 VR will make an appearance during Xbox’s E3 conference, and it will be a ‘Play Anywhere’ title. Long-term, VR will make use of cloud processing to improve rendering capabilities.
A final reminder, this is speculative based on comments from Microsoft’s partner on VR. One thing is certain, this will be an exciting year for VR and I look forward to being proven right, or wrong, on any or all of my theories.
