It will be interesting to see what these are. There is a lot of potential here, but we might be seeing repacks once again. I'm thinking at least one of the two will be repacked either way. I think the Jedi/Clone setup sounds reasonable too. To be honest, even though we've seen plenty of them, the majority of both the Jedi and clones from the ROTS line were pretty well done - and if we didn't already have them, they could make pretty good 2 packs.
ROTS Ki Adi/30th Galactic Marine
ROTS Pilot Obi/Commander Cody
ROTS Yoda/ROTS (or new) Gree and/or BARC Trooper
ROTS Plo Koon/ROTS Clone Pilot
ROTS Aayla/ROTS Bly
Basically a few ideas that people have already suggested - but it might be a way to keep ROTS figures out there (like Hasbro seems to want to do) without having so many H/V and Greatest Battle assortments. Overall, the kiddos (and collectors) want clones and Jedi, so this might be a good opportunity. We'll see.
