I still don't get what's the problem with releasing 3 sizes of a similar product. Xs Mini / Xs / Xs Max iPad Mini / iPad / iPad (Max) Plus The iPad Pro naming scheme is just nonsense, because it runs similar iOS as the base iPad. I know the MB and MBP also run the same macOS, but that's a little different case... Of course, the bigger device, the more space to implement some extra features. Ok, why not? Xs Max could have Pencil support, 3 cameras. Bigger device = bigger battery. Etc.
