802.11 AY will be available soon (IEEE revcom voting on final approval this Friday and then official publication of standard usually ~2 months after final approval) which improve the bandwidth per stream from 11 Gbit on 802.11AD (WiGig just another name for 802.11AD standard) to 44Gbit on 802.11AY. It still not going to have as good latency as a wired connection but at least the theoretical bandwidth is close to HDMI 2.1 levels.
Distance will also be improved to a level that if there line of sight it wont be a issue. It still not going to be able to go through walls well but as long as there line of sight it should be fine.
On average about a year from publication to product in most cases for IEEE standards (Main home Wifi like 802.11AX,AC etc is an exception to this rule as products usually release when the standard still in draft form. 802.11AX routers been available for over a year and it only got revcom approval in February of this year and not even publish yet but expected to be in April).
So it not that unreasonable to believe that in second half of 2022 we start seeing VR headset that actually a decent experience connecting to a computer/console wirelessly.

What Sony can do is put the final reproject stage on the headset. PSVR generally renders in 60 fps, then reprojects each frame twice (shifts it slightly to align with latest head movement) to get low latency 120 fps. That part can be done on the headset, then you only need to send 60fps through the air and the headset can provide latency free 120 fps (at least latency free matching head movements)
Maybe PSVR 2.0 pro could be a wireless version, although it would mean another breakout box. (Unless a ps5 pro with 802.11 launches alongside, options). The annoying part is the battery, where to put it, how long can you use it, how much weight does it add etc. Maybe one on each side you can swap out with two that are charging.
Cable for now, cheaper, lighter, smaller, lower latency. Tie a whack of helium balloons to the cable so you can't step on it :D

Yeah agreed very unlikely PSVR 2 will not be wired. The only question is could they make a wireless addon with it. It would be tricky through on a PS5 since having it plugged into a 10Gbps usb port would not be enough bandwidth. The only way I can think of doing it is having a 802.11AY dongle with HDMI 2.1 in and out and the dongle be capable of hdmi 2.1 passthrough when not in use.
A PS5 pro with it built in would defiantly Simplify it.
EDIT: actually now that I think about it I don't know why I thought that would be hard to do, I mean that how the PSVR is being wired to the console anyway so defiantly possible to make a 802.11AY add on if they was so inclined.
