At IGN, they found PS3 trophies revolving around Arkham City that has Robin as a main character chasing Harley Quinn. Here's the link:

Hopefully this is revealed to be actual story DLC and if it is... words cannot describe my excitement.

What are your thoughts?

Oh, cool! Gonna pick this up!

They did say more DLC would be coming when the WiiU version is released. Or something to that effect, anyway

@Adnan: I doubt they'll wait until the release of the Wii U to throw out new DLC. That's too large of a gap.

Sounds like I have a reason to return to Arhkam City.

@TheGreyOutcastX: Indeed, let's hope it's not challenge rooms but from the sound of the trophy descriptions, I'm hoping for story.

@Deranged Midget: God, I hope so. I liked being able to play as Dick and Tim, but challenges get old real quick.

@TheGreyOutcastX: Indeed, I liked how Dick played differently from Bruce and Tim, but I hope the DLC allows for maybe new areas if it is story.

@Deranged Midget: New areas, and maybe being someone other than Bruce. That would be nice.

@TheGreyOutcastX: Well one of the trophies lists completing tasks as Robin, so I'm hoping he's the lead character in the DLC.

@Deranged Midget: That would be great, and giving that Tim appeared in the story once in a clip, it would make sense if he was the next character to be playable in the story.

@TheGreyOutcastX: Indeed, Dick never showed up and I was a little peeved that Tim played such a small role.

@Deranged Midget: I was more peeved that he looked like he was the mixture of Eminem and Damian. Was not a fan of his robin costume. But yes, both Dick and Tim should have played more of a role in the story.

@TheGreyOutcastX: I didn't mind his look perse, it fit the Arkham universe and I'm glad he was portrayed as being older.

@Deranged Midget: It fit, but he didn't need the hood, and the cape seemed too short.

@TheGreyOutcastX: It didn't phase me, I chose to play with the Red Robin outfit so I was satisfied.

@Deranged Midget: I wonder if they will add more DLC suits for Tim and Dick anytime soon?

@TheGreyOutcastX: I'm hoping so for Tim but more so for Dick.

@Deranged Midget: Yea, 2 suits for Dick was just sad.

Finally Rocksteady are listening to the fans and are giving us story DLC for Arkham City. Shame it's not Nightwing DLC as that was the only extra character I downloaded. Didn't have enough points for Robin as well. But this is still great all the same and points to a third game in the Arkham series which is definitely a good sign. Though where they can go from Arkham City I'm not sure. Thanks for finding this!

@Lvenger: My pleasure

@TheGreyOutcastX: Agreed, only time will tell now.

Nightwing or Nothing.

@Deranged Midget: Indeed.

@ReVamp: I'm hoping for this too. Nightwing was such a badass in the challenge rooms that he deserves a story as well. I'm really annoyed that he never got a voice actor as well unlike Tim Drake. Dick's been around longer than him, he at least should have had a voice actor spouting quips at every turn.

@Lvenger: Speaking as a software developer, there's no "finally" to this. It takes a very long time to develop something with the complexity of an Arkham City. If there is, in fact, new single player content on the way, you can be sure that it was planned from the beginning.

I do hope this is actually a story for Tim and not just more Challenge Rooms.

@Crash_Recovery: Arkham City was complex no doubt about that. How long would it take them to create the DLC such as the extra characters, the challenge room and this rumoured DLC in comparison to the actual game itself? Didn't it take Rocksteady 2 years to create Arkham City? And the reason I said 'finally' was because some people, myself included wanted DLC that added to the story of Arkham City. I mean don't get me wrong I've enjoyed beating up and stealthily incapacitating thugs as Nightwing but some Half Life Style DLC that continues the story of Arkham City was something I wanted to see earlier. In any case I'm hopeful that this is the case.

WOOT! This gives me a reason to play AC again!

This is a terrible reminder that I still haven't even beat the single player.

Curse you, lack of motivation!

I really hope that this will let you free roam as Robin.

@venomyak: As does everyone else.

@Deranged Midget: As in free roam Arkham City like you can with Catwoman? That would be brilliant.

@Lvenger: Indeed it would be, Challenge rooms are ok, but not worth paying for IMO.
