However, As far as we know, him as the fifth Robin, and eventually, There is a possibility of Damian appearing in Arkham Knight because 

1) Talia hinted in Batman: Arkham City that Bruce Wayne and her got intimate one night in Metropolis.

2)The Damian Bruce, “father-son” theme would also seems Logical, going by the Arkham Knight trailer. The will of Thomas Wayne is read via Voice over narration, and it suggests that Bruce Wayne has to live up to his father’s legacy at the same time it is pointing to Damian Wayne

3) The most importantly few months back where Arkham Night Clip was released for the IGN journalist and several other gaming journalist for further deatials click on this link: http://batman4fanatics.blogspot.com/2014/03/batman-arkham-knight-real-image.html

 There were quoted saying " there is a scene where Batman is surrounded by 52 of his villians and he will be facing it with his own Gang" what does that mean well according to me Batman will need his whole gang to deal this Arkham Knight.
