Well we learned that Wogra Woodrata is the Separatist, likely the same species as Tonbuck Toora, that was in the scene on Geonosis when Obi-Wan spies on Dooku and the Separatist Council. Woodrata is therefore what I think many of us here (myself for certain) were voting for when we picked Toora. I think Hasbro was confused on that one as well, and now it's getting sorted out. Everyone wants the Separatist Council Member of course. If Toora is a different species, she (or he?) is even less significant as just another Senator.
Padme Senator (AOTC) actually needs 2 figures. She is appearing this way on The Clone Wars, and she wore the outfit for 2 scenes in the movie (Chancellor Palpatine's Office, and her first reunion with Anakin in her apartment, immediately thereafter). I think there's a strong chance we'll see at least one version of her made wearing this outfit - and the movie one is most likely as she's not action-oriented in this apparrel.
The Ranat (Reegesk) is pretty likely in my opinion. Cantina aliens are always popular choices for production.
Treva Horme should be made. Cloud City is an environment that should be thoroughly mined to really delve into the Classic Trilogy. Star Wars needs to do this to keep OT fans engaged and possibly even later to RENEW the OT as the "new trilogy" to keep the fans who are new now (because of Clone Wars) engaged in SW later on, as the "rediscover" the 'other movies.'
Dofine is a risk of course, but how about a TPM Ultimate battle pack?
The center piece is the re-release of the N-1 Fighter with kid-Anakin piloting it past the Trade Federation ship's bridge. Watching the ship blow by their viewscreen is Tey How, Daultay Dofine, blue pilot battle droids, and red security battle droids! That'd be a nice looking set if you ask me. To add color to it, you could make the scene when the ship starts to blow up, too.
