I was a little wary of animated style figures at first, but have really come to like most of this line so far. So, after seeing Clone Wars and flipping through the Visual Guide, there are some figures that must be made in this style.
I'm going to avoid listing figures that would just be repaints of the base Clonetrooper and Jedi Council members, since it's pretty much a given that those figures will be made if the line lasts long enough.
1. Scout Clonetrooper - the armor worn by the two scouts who did reconnaissance for Anakin to find Jabba's boy. They're the Ep2 equivalent of the Kashyyk Trooper, but with a completely different, and much cooler, helmet
2. Admiral Yularen
3. Mon Calamari Jedi - from page 120 of the Visual Guide (see attachment) and I assume he/she will be visible in an upcoming episode
4. Dwarf Spider Droid - I don't know how they would release this, probably in a Battle pack.
5. OOM-9 - we need someone to grab our Battle Droids by the back of the head and point them to where they need to look (one of the biggest laugh out loud moments for me).
6. Jabba's Nikto Guard - there were three of them who greeted Anakin and the animated styling definitely agrees with them
7. Jabba's Weequay Guard - another cool animated version of an OT alien
8. Ree-Yees or Ask Aak (the Gran Senator) - the animated styling agrees with these guys as well.
9. Jar Jar! - check out the Visual Guide, he looks awesome!
10. 2-1B - I know that he only showed up as a hologram, but they can do a holographic variant later.
Other big stuff:
1. Jabba the Hutt - of course
2. Ziro the Hutt - people can just buy him and pretend that he only speaks Huttese
3. "New" Y-Wing - not sure if this is already confirmed or not
4. Tri-Droid - it just needs to be larger and less bendy than the current version
