Theres no way ASUS stifles support on a
new BCM platform for a PRO moniker. That doesn't make sense in my head.
Hell, the original AX88U was launched in 2018 and still gets updated fairly often.
Broadcom seems to keep their "high end" platforms for 2 generations.
A53 4906 and then 4908 were launched with ACW2 and is/was supported with Gen 1 AX.
A53 4912/4916 is launched with Gen 2 4x4 6715 and Newer 675X SoCs.
Marketing docs indicate 4912/4916 will support early WIFI7 Hardware, though theres competition in this area as even MediaTek offers A73 via filogic 880

4x5 MIMO on 6G is interesting.
