Will be interesting to see who comes out with the client HW.
At the bottom of the page I linked to above is quite a list, in the 4 major categories, of "Devices", including Chipsets that are out by what manufacturer that are capable of the newer tech.
"OTHER COUNTRIES STILL HAVE TO APPROVE UNLICENSED 6GHZ USE"
"And assuming this all does work out, you’ll still have to replace your devices to get the benefit. Current gadgets aren’t set up to use 6GHz networks (it’s largely been illegal to broadcast, after all), so you won’t see the benefits until you buy a new router and a new phone, laptop, or other Wi-Fi-enabled device that can connect to it."
So for users asking about if Orbi AX will be upgraded to 6E...Ah no.
