Who says it can’t be used on pc? It uses a common usb c cable so, or Sony will support it soon after launch, or someone will write a driver for it to make it work, like ds4windows e.g.
If Sony doesn't sell an adapter themselves, at the very least someone would need to make it work with a "reverse" USB-C -> USB3 + DisplayPort adapter, and those will take a while to appear because AFAIK they don't even exist in the market.
Otherwise I guess the headset can only be used by the owners of reference 6800XT/6900XT and/or future 7900XT GPUs (i.e. GPUs with USB-C outputs).
I'd actually be okay with that because I own a 6900XT, but I doubt the owners of reference Navi 21 cards present a critical mass for PC adoption.
It's beyond me how someone would spend nearly 500 euros and play with DS4 only, honestly. You can't even move your hands freely lol
PSVR1 however was clearly a entry level experience. Even with Moves we ere talking about old PS3 2008 controllers not designed for VR. The whole package was very experimental and made the most from already available peripherals.
On my PSVR I played Astro Bot, Battlezone, Bound, Driveclub, Keep Talking and Nobody Explodes (
way too many hours with friends & wife on this one), PSVR Worlds, Resident Evil VII and Until Dawn: Rush of Blood.
I only used my Move controllers on that last one.
