Along with what is the obvious and what we all know will be kept such as the full size Air and the Mini Retina, Will Apple in your opinion come out with newly designed iPads to go along or fill in with these? What do you see going on if so?
Seeing that the leaks seem to unify the design between the 4 devices (iPod, iPad Air, iPad Mini, iPhone) I would say this design will be around for a while with just small changes year to year to freshen them up.
