So this is pretty big imo and it was posted in the OT and I just tried it myself, essentially this allows you to play Steam VR games either through wi-fi or USB (USB-C being the fastest connection) and after testing even wi-fi latency on my 5Ghz connection away from the router was perfectly acceptable and I was super impressed. This honestly to me improves the value of the Quest pretty significantly as you now have the Quest Store and Steam for your VR library.
