Not sure I understand the point within this comment. It's a massive improvement for anyone who doesn't have a high-end VR headset. That can be considered a massive improvement for PC owners with low end/no headsets, or no improvement to PC VR users at all because PSVR2 requires a PS5. Their circumstances remain exactly the same, neither improved nor worsened.
I
think your point is that PSVR isn't bringing anything new technology wise, just offering a nice package for those who haven't had access to the high-end VR headsets. I don't know that PSVR needs more and better tech, especially considering it's already pricey. And I think VR in general needs a large high-end market for next-gen content, which a new consolidated platform might usher in. If so, that might do a lot more for the PC VR player with their high-end headset than their $2000 8k hardware brings, a massive imprvement in VR content.
