It will definitely have 120Hz! I’m only saying this because I want to be that one guy that says something contrary to everyone else in this thread.
Honestly, if it doesn’t have ProMotion (and it’s looking like it won’t) i’m going to have to pass. I’m so use to using 120Hz on my iPad Pro and have been eagerly waiting for Apple to update the iPhone which will happen this year. It would be my dream if they made an iPad Pro Mini with pro motion, OLED (I’d take XDR as well) and apples latest chips. I would resort to getting the standard iPhone pro instead of the max and mostly use the iPad Pro Mini as my daily device.
