A fresh model from ASUS based on Filogic SOC (based on reviews found in the web, I don't own the actual hardware now)
It looks similar to ASUS TUF Gaming AX4200 (support thread Asus TUF AX4200 support), but with one additional 2.5G for LAN, 6 instead of 4 external antennas and 4x4 streams for both 2.4GHz and 5GHz
While it should be supportable, someone[0] with the device on their desk will still have to do the porting work.

[0] this "someone" might be you, yourself - it's going to be a steep learning curve, but judging from the TUF-AX4200 and the pending RT-AX59U PR there shouldn't be anything particularly bad about it either.
I'v jut bought this one. To support it with OpenWRT, I think most of the AX4200 support can be reused. Unfortunately, ASUS hasn't released any GPL source to it. In discussion with Asus support, they said they are not obliged to do so. Typical reaction I guess.
Hope I can base the OpenWrt support on the decompiled DTB and the AX4200 support...
'Easy' or not, at the very least it needs someone (and in all likeliness, that someone would be you, yourself) with the device on their desk willing to work on it. Lacking that won't get you anywhere.
