Is The Dark Knight still the Dark Knight?

I think that the intent for The Dark Knight's ending was to pursue a different angle for a future third film. At the end of TDK, Batman is now the hunted. He will no longer be deemed as a hero to the public, but rather, a vigilante who terrorizes the streets of Gotham. This leaves several angles for the plot of a third installment. For instance, because Batman is wanted for the alleged murder of Harvey Dent, this means he will have to keep a low profile. Either we will be seeing more of Christian Bale in the next installment as he plays more of Bruce Wayne the Billionaire rather than Batman, or it could also mean an opportunity to introduce some new villains into the picture who could wreak havoc in Gotham, forcing the police to seek out Batman for help.
