I'd like to see them announce Series 10, which is hopefully ROTS and then they'll get back to the OT stuff. I think they'll release the Shadow Guard as the exclusive.
I'm hoping for a Droids boxed set. They've snuck enough stuff out, they could do the box next. It would be awesome if they did a couple of the unreleased Droids figures in the box set, like Kleb Zellock. I'd eat up just about anything related to Droids. Fromms would be awesome, Vlix would be freaking stellar.
I fear the next progression may be the Ewoks series, though the Bearbrick releases may pre-empt that happening (I hope).
