What Will Apple Do Next With The iPad?

First off, i'm getting it. I have the 4th gen. and held off from the Air in anticipation of a much better version of the Air next year. What should I expect, though? I assume Touch ID is a given along with a masterful A8 processor. That alone would make me satisfied but there should be more in the pipes. New software tricks in iOS8? New, unseen before hardware developments? What are some of the writings on the wall that you've seen that allow for some substantive predictions?
