It'll be only one usb-c wire. Honestly wired is better in almost every way because you talking about putting PS5 tech in a small head unit. shyt wouldn't work and would be heavy as hell. One wire just messes with your mobility and even then if it's a good 7' it wouldn't even be in the way. You got cables that's 10' and 20' long too, so no big deal in my eyes.
The PSVR2 is in a whole different realm, in no way can the Oculus compete unless you a casual.
I'm not even into racing games, but I can't wait to try shyt like GT7 and Ride 4
It wouldn't need all of the PS5 internals for it to be wireless, Just a decent ARM processer, Wifi chip and a battery
Games like Eleven table tennis, and thrill of the Fight just scratch the surface of total room scale tracking.
I think the true future of VR is actually in full body/room-scale tracking and in high quality AR,
It would be nice if PSVR2 had tether less room-scale.
