I've finally been able to test this and have confirmed that iPad Air cases aren't fully compatible with the new 2017 iPad. The volume buttons are shifted slightly and the camera as well. Can you use it? Yes. My leather iPad Air Smart Case fits the 2017 iPad in a usable fashion, but changing the volume will be a bit weird. The camera hole being shifted slightly looks weird but doesn't seem to affect photos. Have a look for yourself; I posted photos.
