That's the conundrum. It's a niche product. It's expensive as hell and money is generally tight. Games take long to make and cost a fucking ton. Do you really want your top studios spending 3-5 years to develop a triple-A game to be played on VR with a installed base of half a million? What about the other 25 million players who own a PS5 but not a VR2? How do you support them too?
This is a niche product and will continue to be. World is not ready for vr and no one figured out those to properly support it yet. It's indies indies indies, an extra mode in a 1st party game and that's it.
Anyone following it should've seen it coming. VR is still a niche, especially with the high price tag. To top it off Sony didn't really have any "killer" apps to make the thing a must have.
I think VR has a tough battle to fight in the sense that I think most people prefer 2D/non VR experiences because they can play them longer and without sickness. VR is cool and has a wow factor when you use it, but it's still hard to get into something VR for more than 20-40 minutes before feeling sick and headachey, at least speaking for myself in this regard.
That, and depending on the game there is a very real sense of 'flight/fight' that you are less likely to feel with 2D gaming. Case in point, the difference between playing something like RE Village 'flat' and in VR. I'd love to experience the VR version but I don't know if I could stomach it for more than a few moments at a time. Generally I have to be in a certain mood to commit myself to a VR session vs just picking up a controller and playing on a TV.
I think another thing is that a lot of people, myself included, don't actually want a fully immersive headset experience. I like being able to pause my game and talk to my wife, etc. The headset adds an additional barrier to the outside world, and I'm not sure it's one that many people want.
