Definitely don't want a prequel. There's still so many things they can do by moving this game forward with the story which have been mentioned throughout the comments already. If this is the way it's going to be an mark hamil sticks to his guns and doesn't play the joker, there is only one replacement and only one. John DiMaggio. Don't get me wrong noone can touch hamil,s joker but John does a damn fine job of making the character his own.
