Hello,
might be a strange question but what are the chances that the Asus GT-AX11000 will get a working openwrt version?

It is using a BCM4908 SoC with three BCM43684 for Wifi and AQR109 for ethernet.
Since this is a 64 bit plattform, i guess there is still a long road to get that running correctly, am i right?
