I'm betting on Maul for the next one. If not, then EIII Anakin or Obi Wan. I'd love to get a Vader next (Never bought one in the Hasbro line and don't have 200 bucks to spend on one fig of RAH) but I doubt we'll see him that soon.
Anyway, who do you guys think will be next. I heard someone mention that there would only be Jedi figures this year but that doesn't make sense to me (since they're doing half and half of OT and PT and the only OT Jedi would be Luke, Obi, and Yoda) so I'm thinking any character might be fair game.
