Robo was before my day and ED has always been way too much and defective so I'm excited for the new version and Arkham City for sure as it's w/o question the definitive Batman for me. I definately want a Mark Hammil Joker, and if they make her, a Catwoman.
HT has already said they hate Catwoman but are working on Harley (barely convinced themselves to make Cathaway apparently). It will probably just be Batman, Joker, and Harley in this line.
