I am always confused when people assume that redesign would mean something dramatic. What would they expect? Apple's laptop design always pursued the same vision, and they are closer to it then ever. From the design language standpoint, the MBP did not change that much in the last 12 years. So sure, we will get a tweaked geometry, some bits and pieces here and there, but I don't think that the next iteration of the MBP is going to be a dramatic departure. There is just no function in that. Those images in the 10.15.1 look just about right for a 2020-2024 redesign.
2019-2024 redesign, darn it!
