If nothing else, it is a 4 channel readout sensor version, and that has certain difficulties with specific types of noise that are less of a problem with 2 channel readout.
Of course, the circuits are new, the wiring and layout is new, and the Prime processor has also changed, so it really is a new image processing path.
This is not quite like starting from zero, but it is not a slam-dunk either.
