Interesting, but I'd like to hear more about what else it'll be doing, as well as price.

Still, this should be more about the headset itself, rather than another PSVR thread. (We seem to do this every time we mention a new GPU/CPU on here) 

Well, it seems to be a normal Vive pro with some little improvements here and there. I imagine they can maximize the pros clarity by enabling ludicrous amounts of super sampling in the fovea spot (like 300%+), but other than that it's a pretty known quality by now.

The normal pro costs $800 (headset only), hopefully this one comes in below $1500.

Yea, eye tracked foveated rendering (ETFR) would be an extremely good tool in a console environment and I personally hope that is Sony's focus over wireless VR implementation. The reason why I think these techs are not really compatible at this point is the extremely low latency (<2ms) and super high bandwith needed for ETFR to realiably send back and forth the gigantic amount of tracking data (especially if they include 4+ cam inside-out tracking, which is my guess) aswell as the video/audio streams, which I think wireless connections aren't ready to handle. Maybe some sort of laser connection can do it in the future.

The headset will need some processing build in for eye tracking and inside out tracking. That way it can reduce the data to a simple x,y,z + yaw,roll,pitch vector with x,y for eye position. It would be a waste of bandwidth to send all that video data to the console to be analyzed. The last second reprojection can also be done by the headset to remove any lag with head tracking. Then the headset can double the frame rate locally.

Wireless also has the problem of power supply. Batteries add weight, which adds discomfort or hassle by having to carry the battery pack on your body. Plus it adds costs as you still need to transmit at least a 1080p60 stream to the headset, likely 4K60 next gen, while compression and wireless transmission adds extra lag plus compression artifacts are more visible when blown up to 100 degrees fov. 1080p60 8 bit is already 2.8 Gbps of uncompressed data.

You can always offer both or a wireless add on, like a replacement cable with small battery pack to be carried on your body.

Hm, good idea, but a bit pricy to realize. Maybe Sony will release PSVR2 as a wired headset, but with the connector cable being able to be popped out at the HMD (would good to make that one replaceable anyway). And then 1-2y later they could release a (pretty pricy) wireless upgrade box that connects there and has the necessary processing power + batteries as well as the antenna. That would mean the PS5 would still need to reserve the processing overhead to do all those calculations itself for the wired users, but I still think that is a good way to offer wireless for the enthusiasts while keeping price in check for the base unit.
