Dude, we got that kickass Battle Arena set with them in it. What more could you want?!?
Sarcasm aside, and believe me when I say this comment even makes me roll my eyes at myself, I actually like the Palpatine that comes in the Battle Arena. As cheesy and statue-like as it is, I don't think it's that bad a figure.
Okay, so it's bad, but it's still neat to look at in all its crappy glory, unlike the Mace Windu, Anakin, Dooku, and Obi-Wan figures in the BAs.
As for what I'd like to see, I'm not up on the ROTS characters (I've managed to mostly stay away from spoilers), but here's what I would like to see:
-More Clones (this goes without saying and works on the assumption that Hasbro will actually figure out their case assortments)
-More Padmes, from ROTS, AOTC, or TPM. Seriously. There is no excuse as to why she keeps getting short-changed.
-Palpatine in the robes from the 12" Darth Sidious doll.
-The other two medical droids from the Vader construction scene.
-Queen Organa with Leia
-Beru Lars with Luke
-Anyone else with the last name Lars (and if they have to do OT figures, please redo Owen)
-Grievous' Bodyguards (I'm probably alone on this, but based on the shot of one in the trailer flanked by BDs and the few still photos I've seen of them with Grievous, it looks as if the current version is smaller in both height and width when compared with the photos/footage. Plus, it'd be cool to have a staff that had the glowing effect on the ends of each thing too.)
