I hear ya, but I have a gut feeling that some of the film's imagery will surprise a lot of people. While I don't think it will be explicitly graphic, I believe Nolan will find a clever way to make things scary, disturbing, dark and unnerving while still keeping it *just* passable for younger audiences. Clearly, he knows kids will see this film. It's the Goddamn Batman. Still, Nolan would never compromise any kind of integrity for that. So yeah, we'll definitely see some... escalation, if you will, with the violence.
