05 EpV Boba Fett & Stormtrooper
Sgt. Doallyn would be awesome, but I'd prefer Brock Starsher first (the white-suited guy from the skiff battle with the same helmet) since Bane Malar scratches many of the Doallyn itches. But updates to Hoth Luke and Han to include alternate heads from their recent figures would be great – Luke needs the scarf, and Han needs to have his hood up when riding the Tauntaun.
The next 6" figures sound great as well, with two potentially huge figures coming via Vader and Chewie.
Hopefully the Mission Series Boba and Stormtrooper is just a repack of the Saga Legends figures since those are proving difficult to find (for now, anyway).
