I am not even bothered about 12 Pro Max or even 13 Pro Max for that matter with my 11 Pro Max! Current form factor sort of hitting its limits on innovation.
I love XS Max design and the cameras all look excellent. 12 is probably for 6-8 owners. Certainly X generation can skip this one unless they go for bigger screen. Mini is a great compromise for those from >= X - 11 family.
My number 1 reason for upgrading my XS Max is for the Qualcomm modem. My intel modem on Verizon still disconnects Wifi, Bluetooth and occasionally my network service.
