Flash on the back of the iPad near the camera, faster processor, more RAM, possible exterior re-design making the bezel thinner, um...that's all I can think of.

Apple's experimenting with a new kind of authentication by asking the user to identify faces from your contacts to log into your phone. Also, in the iPhone 6, there'll be a fingerprint sensor for authentication, so a sensor for the next gen iPad is possible.
