I'm hoping they don't make people double dip on an AA/AC Batman. Since they have both licenses, if this does mean "C'est la vie" to the HT figures, and SSC does a Batman, I really hope they include alternate parts (belt, boot tops, gauntlets, and accessories).
Honestly, though, my wants would probably be:
Batman
Mr. Freeze
Catwoman
Joker
Robin
Ra's
I never thought I'd say this but I'm really hoping someone picks up the Origins license, be it SSC or HT. Some people dislike it because it's not Rocksteady, but it's got some of the best character designs this side of video games, and I could see figures kicking some serious ***.
