I am not exactly a Robin fan but I have no issue with him being in the game in some small capacity.

A cameo of Robin wouldn't be bad at all. I hate all these people bitching. Robin is a very interesting character with tons of pathos.

oh yes.
 
HATER GONNA HATE!
 
GREEN PANTIES AND PIXE BOOTS!
ITS ALL I AM ASKING!
 
And maybe this is the time to showcase UE3 thigh rendering capabilities!

if its tim drake or damian wayne in this, im all for it. jason todd.. not so much.. but i doubt that since the original batgirl is now oracle.  
 
robin is a great character if you follow the comics

Not a big fan of Robin myself, but like someone said,  (paraphrasing) I trust Rocksteady not to F it up. 
But I definitely don't like Co-op.  I hope they don't do that. 

FUCK!

Maybe Robin will pop in and out of cutscenes and go handle something else off screen. If Rocksteady sticks with the timeline (which seems likely), Tim Drakes version of Robin could be a good addition as long as they keep his appearances limited and they don't make it co-op.

The games IMBD listing suggests Robin will enter the fray in Arkham 2  According to the listing, the character will be played by Vincent Martella who has recently worked on the English dub of FFXIII.

So that's a mistake but their is a cancelled flying graysons poster in Arkham City. 

Though it might just be an easter egg like the ones for Vicki Vale, Carmine Falcone, and Max Shreck.

Robin can be good, you just need to read more Batman.

I saw this thread. I got happy. Then I got sad.

The latest issue of Games TM (103) not only gives us a Batman: Arkham City cover story but also the provides us with some comments from Rocksteady's Sefton Hill on the caped crusaders side-kick. Sefton praises recent comic iterations of Robin, claiming he can be "interesting and exciting" and if done right, "he can be a fascinating character"

GameInformer has already reported that when playing the game they caught a glimpse of a Flying Graysons poster, but take that with a pinch of salt in terms of Robins inclusion in Arkham City.

Sefton Hill's quote when asked about Robin:
"... there's a chequered past for him, but I really feel that some of the latest iterations (of the character) in the comic book universe are really interesting and exciting. I don't really want to say much more than that, but I definitely feel that -- if done right -- he can be a fascinating character".  

The only time Robin was bearable was when Stephanie Brown was Robin.
