I don't think Apple will do inductive charging. It doesn't really solve a problem, as you have to have a pad plugged into the wall anyway, and you'd have to bring the bulky thing along if you wanted to charge. I think they'll skip it and jump to true wireless charging when that arrives.
I posted this in another thread, but this WSJ article leads me to believe we will not be seeing NFC this year.
Maybe the new iPhone-only feature will take advantage of the larger screen in some way. Group FaceTime chat? Would make sense if they upgrade it to a FaceTime HD camera.
Group FaceTime chat makes sense as that would compete with Google+ hangouts. It could be activated in the same way as conference phone calls. They could make a big deal about FaceTime at the keynote with the new FaceTime HD camera, FaceTime on 3g, and Group FaceTime. Maybe more people would use FaceTime.
