Cat woman in modern days is seen as an ally to batman tho, and a romantic interest. I wonder which way nolan will play it, maybe a more anti bat catwoman at the start, bane kicks the living hell out of batman, maybe does not break his back entirely. Town goes to hell in a handcart and catwoman picks up the "good" mantle, her and bats take down bane.
Bane is sort of an interesting character in that he kicked off a long roller coaster of "breaking the bat" in fact he literally broke him, coming closer than any character of physically breaking him, most every other trial of breaking batman has been mental, darkseed, the black hand/mask or wth ever they called themselves, the joker throughout the years over and over, but bane stands out as one of the very few that challenged the bat physically. Killer croc maybe on a good day but croc seems way out of the realm of nolans gritty "real" world, especially if he balked at using the penguin. Bane also has smarts, lest in some of his arcs that croc lacks entirely, making him more than the raging roid rage hulk that some writers demoted him into. And bane has a rabid obsession with the bat, one thing he shares with the joker, but banes focus is more singular, where the joker would burn the whole city down to get at batman.
And in a world where a guy dresses like a bat, and his nemisis dresses like clown, it does not seem all that far fetched that some girl in a ski mask might thing to fit in dressing like a cat to be a cat burgler would be in fashion for gotham. Bane will be really interesting to see the mask not so much but how nolan handles the whole steroid thing and will bane be digitized to go form average guy to hulking beast when he starts juicing.
Beyond that lets hop nolan has one more homerun to hit for this movie, all the pressure and expectations after tdk cannot be easy to deal with, at this point it is far far easier to fail than it is to succede.
