In all honesty I don’t think Apple are going to release any new iPad Pro’s until mid-late 2021 now, I think the Pros will skip the A14X altogether and go straight for A15X just after the next iPhones, I think this will be an iPad Mini refresh.
My predictions of hardware for 2021 are:
March - iPad Mini, Apple TV, AirTags, AirPods, AirPods Studio.
June - Mac
September - iPhone 12S, More MagSafe Stuff, Maybe Apple AR Glasses
October - iPad Pro, Apple Pencil 3, Magic Keyboard 2
November - More Apple silicon Macs
