Well Grand Turismo sport had been boasting about VR capabilities prior to going on sale, but sadly VR implementation is a bit of a disappointment for a lot of people who bought it for this feature, even after two big updates, the VR portion of the game is still exactly the same, as in limited to two lap races against a single AI in arcade mode.
I suppose Polyphony are getting numbers from Sony on how many people who own GT Sport are actually using a VR headset, and they are basing future VR updates on when it reaches a predefined mass before those updates are given the go ahead.

Which makes me wonder, if after Polyphony has had so much time to build the VR portion for GT Sport and has only come out with what it has to date, if VR on the Omega pack will work when playing online?
If it does, will a standard PS4 be up for it, or will those with a PS4 pro be getting a much better experience.

I'm guessing the VR update will be released around the week or fortnight before the HD/FURY /2048 PS3/VITA servers close down, it would seem the best for Sony, impact wise, as a lot of people will be thinking of Wipeout one way or another over that time period
