I hope the ipad pro air 3 doesn't have a higher res screen. If developers are optimising for the ipp 12" screen, then using a similar resolution on the smaller 9.7" screen may be uncomfortable to use. Keep the same resolution it currently has, so it is in proportion to the larger ipp - bigger screen = more real estate not just bigger pixels.
That could also allow them to use a slightly lower clocked CPU as it wouldn't be pushing as many pixels, which would also help the battery life.
