It's not definitely Catwoman. That isn't 100% confirmed.
MoviesOnline: You’ve done Scarecrow, you’ve done Joker, Ra’s Al Ghul, and now Two-Face, if you were to do a third film, which characters would you like to tackle?
DAVID GOYER: We’re not going to tell you other than to say Batman has been published for 70 years. In the first movie we used Ra’s Al Ghul and the Scarecrow who had not been in the movies before and had not been in the 60s TV show and there are dozens, if not hundreds of other characters that fit that bill. Everyone says you have to use the Penguin or Catwoman. Well, I completely disagree.

This doesn't really say anything against Catwoman, it says that there are many others to do besides the ones you've seen over and over again.
