Batman 3 Villians

Now that the release date for Batman 3 (or whatever it's going to be called) is set for July 20, 2012, let the debate begin: Who will the Bat battle next?
The Joker is presumably locked up in Arkham Asylum, and while there is always a chance that director Christopher Nolan will recast the part, he might want to leave the late Heath Ledger's iconic performance as his final statement on the character and move on.
