Is it safe to assume that Catwoman won't be wearing Prada?

Big casting and villain announcements today on Christopher Nolan's next Batman movie. Various reports say Anne Hathaway will be playing Catwoman (or at least the woman who becomes Catwoman) and Tom Hardy of "Inception" will play Bane.

I'm a bit unexcited, both with the Hathaway casting and Catwoman as a potential villainess. But in Christopher Nolan I trust, until he makes a movie that's less than awesome.

I know I'm in the minority here, but I think it would also be a ballsy move for the Joker to return as a different actor ...
