hmmm the game itself seems fine but the batman name and theme definitely seems tacked on and while that may increase awareness and popularity of the game and thus make it do better sales wise, im not sure if that was the best move for the actual game in terms of presentation and actual game play. 

From what i've read ( including an article on gamespot, http://e3.gamespot.com/story/6316489/batman-arkham-city-updated-hands-on-preview/?tag=updates%3Beditor%3Ball%3Btitle%3B1 ) she has a separate narrative but it takes place simultaneously with that of Batman's. basically you play certain story sections as her  (something along the lines of 10% of the whole story) but i believe you will also be able to switch to her and just roam the city and she has unique side missions. plus certain riddler trophies can only be obtained by using her character.  Also she will fight and move around in a completely different manner besides the ceiling climb :  " Catwoman will take a much more physical approach to getting around that relies on her trusty whip, parkour-like moves, and good old fashioned climbing and jumping"  
she also has a different detective vision (thief vision) which focuses on things she can steal and so forth. and ofcourse as you can see from the trailer she has a much lighter and faster fighting style with more flashy moves. plus she also has her own gadgets and a mini progression path in terms of upgrades.  
 
all in all its looks pretty awesome, it looks like they have created a whole other playable character and not just a re-skinned batman. cant wait for this game to come out!
