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
