Highly highly unlikely.I am really hoping that the next version keeps a 10"ish screen but packs it into a frame the size of the original ipad pro. One of the things that kept me from going from the 9.7 to the 10.5 is the increase in both physical size and weight. If they return to the 9.7 physical dims I will update but for me bigger/heavier isn't better.
I see a 11” same 10.3 chassis. 12.9 smaller chassis.
My dream iPad (you’d like this too) take the mini and lose the beZels. Someone did the math and you get close to a 9.7 inch screen in the current iPad mini chassis.
