The Luminara/AT-RT Driver and Anakin/Blue ARC sets are a big pass for me. The use of the 2003 kama on the blue ARC, as Adam said, just looks horrible and it's easier to just get a few more of the comic pack ARCs instead. This camouflage stuff is getting almost as ridiculous as the Skittles Jedi Starfighters.
I'll definitely be picking up the other four sets, though, although I have to wonder what they're going to repack for Obi-Wan and Palpatine. I would assume that Hasbro is going to go the cheap route and slap the 2005 ROTS Palpatine (number 12, I think) in that set, but with the "ARC Commander" (or "Here's your 'toon accurate Fordo") being in Phase I armor, I would guess Obi-Wan, logically speaking, would need to be an AOTC era version.
Then again, this is Hasbro we're talking about, so logic has no place in how things are done.
