In Insider #80, with the new Clone Wars on the cover, there's some interesting confirmations as far as the ROTS lines go.
*There will be three action figure series: Collection 1, Collection 2, and Action Series (or something like that). I assume that's this movie's take on deluxe figures (like that odd-looking Palpatine).
*There will be several small battle arena sets with two unique figures from the lightsaber duels. They can connect to each other. I'll bet that's where that hoodless Palpatine is from.
*There will be a Mustafar playset, and the little arenas can hook up to this.
*There will be three vehicle assortments (likely small, medium, and large).
*Attacktix are large figures on bases, with odd-sized accessories and/or body parts. It's like a card game - once a figure is knocked over, you use the powers listed on the bottom of its base. They had pictures of six figures: Wookiee Commando (with enormous blaster), Darth Vader (with large lightsaber), Chewbacca (with a huge pimp hand), Shaak Ti (with what looks like a water ball), General Grievous (with a doofy grappling hook gun), and Obi-Wan Kenobi (with a ginormous arm that shoots something). To me, they look dumb as hell. I'll definitely be passing on these.
The playsets and arenas sound good, I hope the figures aren't just retools of the versions we're getting in the basic line. I know we've heard most of this before, but it's always good to have confirmation.
