So they have already announce a sequel to Batman Arkham city. Dont know if you guys have played it and completed the main story but Joker is dead. Here recently they have released a DLC entitled Batman Arkham city: The revenge of Harley Quinn. And if you have played there is some major foreshadowing. Oracle mentions that Batman has not been the same since jokers death. He wont even talk about it, rumor in Arkham city is that Batman killed the joker. We all know that is not true though. In the main story, the doctor tells Batman that joker keeps going on and on about his last laugh. Why is Batman so hurt over the death of the Joker and he knows it wasnt his fault? Could it be that the Jokers last laugh is BATMANS GUILT? We shall see in the sequel. My prediction is that Scarecrow will show back up, and try to bring Joker back in some nightmare form.
