I just hope Asus is sure about going with this. We ROG II users had lost hope and moved on. If they don't continue to provide A11 updates until the software is stable then this is just adding fuel to the fire.
I have experienced a not so good update experience during OnePlus 3T's last major version upgrade and it left a really bad taste. It was one of the reasons I had moved away from OnePlus to Asus.
