I agree that with Star Wars it will probably be Rebels (I can't imagine anything else it would be), and Ant-Man and maybe Ultron for Marvel. For Disney, I imagine that it could be Tron, Frozen, Wreck-It Ralph, or maybe even something for the Fab 5 (there have been a lot of requests for Goofy, and Pete could be a good edition too. Maybe the Phantom Blot is going to take over Toontown!). Classic Alice in Wonderland would also be amazing! Jeez, I don't which ONE of those I would want the most... Decisions, decisions!
What characters would be likely to come with an Ant-Man play set? I know zilch about the story other than there's a character named Hank Pim, and someone who can shrink to the size of an ant.
