I'm interested in learning about it, but I only see press releases for now.

Also, big question as to whether it offers any advantages over the AX200, which appears to be familiarly stable in Intel fashion. I don't see anything on the surface about supporting WiFi 6e with 6GHz either, and that's really the one thing about AX that would make an infrastructure upgrade worthwhile with respect to the spectrum deconfliction possible.

+1. Right now, I can't see upgrading a WiFi NIC or AP for the sake of upgrade, unless it supports 6e. Anyways, WiFi 5 (802.11ac) is still perfectly fine for most.

Thing I'm concerned about with 6e: you run into the issue of older devices that don't support those frequencies. I'm wondering if we're going to be seeing 6e APs with dual 5/6 GHz radios to support both old and new. It's kinda a mess, too bad the the 6 GHz channels weren't made available sooner to coincide with the introduction of WiFi 6.

Yeah, they're supposed to support both, as well as 2.4GHz. Nice thing is that all of the improvements in 6 / AX apply to all three bands, but the hard part is that there's still lots of stuff on the 2.4GHz and 5GHz bands that will interfere. 6GHz is helpful because of its limited range and its lack of contest from other consumer devices; essentially, that spectrum should be more or less clear for use, and will work even better in higher-density environments.
