The Jabba's Band sets have shown up on WalMart.com.
I consider this a very good sign for getting those Comic 2-packs.
Hopefully Hasbro didn't let WalMart get away with producing LESS of these three sets than any other comic 2-pack and they'll be on walmart.com eventually as well.
Have any case break-downs for these been determined? The standard case holds 8 sets. I could see it being 3x of the clone set, 3x of the Fett set and 2x of the Seperation of the Twins set.
