Besides the set revealed this is what's left san retreads:
Han Solo, Princess Leia, Obi-Wan Kenobi
Hammerhead, Walrusman, Greedo
Tusken Raider, Boba Fett, Snaggletooth
Han Bespin, Ugnaught, Lobot
Leia Hoth, R2-D2 Sensorscope, Luke Hoth
C-3PO Removable Limbs, Ugnaught, Cloud Car Pilot
Take your bets for the other two! My guesss:
Hammerhead, Walrusman, Greedo (Hammerhead new maybe in blue, Greddo all Green no vest)
Han Bespin, Ugnaught, Lobot (Lobot is new and the Ugnaught with Purple Apron and V2 head)
Han Bespin is still and demand and Ponda is really in demand so this would be a great way to get them out again. Like the other sets it would be nice if they tighten up Han Bespin like they tightened up decos in the previous sets.
