Just saw an article on gamespot announcing Catwoman as a fully playable character in Arkham City.
Don't get me wrong I loved Arkham Asylum but was going to wait for some sort of Steam sale for AC just like I did with AA.
This is quickly becoming a day 1 purchase.

YES. Imagine the potential with Catwoman challenge maps. (and the campaign, of course, but what keeps AA in my rotation after all this time is the side stuff) 
 
... Is it out yet? Now? Now?

Could be awesome. 

Awesome. Still, a part of me wishes the rumors of Batman/Catwoman co-op were real, since I'd love playing through this with a friend.

Awesome.

Please for the love of god let it be optional.

Initial reaction is that of skepticism. Could be fun, but it's a strange route to take. Definitely interested though.

That trailer was awesome, or rather: Me-fucking-OW!
 
Take my money already!

Hell to the Yeah!!! My most anticipated title of the Fall.  I hope they make a killer CE of this game unlike that shitty batarang they did.

Mixed feelings. I'm all for solo Batman stuff, but extra content like this can't be a bad thing as long as it's not forced on the player, and Rocksteady has earned my trust after AA. 
 
She's got some slick moves.

If you could chose either Batman or Catwoman and play through the campaign, I'd be up for it.  If it switches between the two, not so much. 

Sounds awesome, here's hoping they will take the RE4 route.

I love that ass 
 
wait, we're not talking about the ass.  
Ok, yeah, sorry, um, yeah playing as Catwoman sounds terrific

Looks hot.

I am stoked since she is one of my all-time favorite "heroes".  I read somewhere yesterday in a hands-on preview that you will need to play as Catwoman in parts of the game, but not an obtrusive amount (maybe 10%) since Batman is still the main focus, however you can take breaks and do optional Catwoman missions to explore other areas and steal stuff.  What they said was that she played a lot like Batman although with more acrobatics and flair.  Her unique moves were a ceiling crawl and use of bolas, caltrops and her whip.  She also has her own special enhanced sense feature similar but different than Batman's detective vision.

Yup, could be awesome.

This is actually pretty good news.

I wonder how it is integrated into the campaign and if you can switch to her optional stuff on the fly. 
 
Considering how awesome AA was, I have no worries. If they pull off an interesting open world, they're set for a GOTY contender.

Could be awesome. 

They made playing as the Joker different enough from Batman very fun, I'm interested to see how they pull it off with Catwoman.

Awesome news, this is definitely the biggest contender for my GOTY along with Mortal Kombat... can't wait!

Yup, could be awesome.

@televisionomy: I'll reserve from passing judgment on how well it's actually integrated into the game until the game is finally out.

I wonder if co-op would come with this sweet package.
