Hmmm. I’m hoping that it means they’re not entirely sure yet about their strategy.
I would expect one of two things:
It could be they are considering requiring PSVR2 on PS5 only games, as it is likely that the next VR headset will support room scale and haptic controllers that harness DualSense like functionality (various patents have pointed to this). In that sense, their policy would match the existing policy on DS5 controllers. It works with the PS4 VR only titles insofar as you can play those fine on the PS5 using all the existing equipment, but this strategy breaks down temporarily for all titles that have VR features added to the main game and are cross-gen like Hitman and such.
This would make the most sense to me, but is also what I am hoping for most.
The other option is that they are completely unsure in what way to proceed with VR. They will be continuing their research but do not have concrete plans yet, and they may change their minds and create PS5 drivers for the existing hardware after all in the new OS rather than just providing them only through backward compatibility as they are doing now.
Either option may be true, independently of each other, and it may just be a matter of not having either solution ready yet, or the decisions not having been made, and in the worst case scenario the decision could be to just abandon all investment for VR support in PS5 titles altogether until further notice.
Could also be that they will create something like Oculus Quest 2 that works both standalone and can link to the PS5 wirelessly with WiFi 6 streaming. Personally I think that could hold a lot of promise too. Their remote play knowhow is in good shape.
Meanwhile Microsoft could, something I would recommend, just start supporting third parties, perhaps starting with Oculus Quest 2.
