I'm not sure how many 6" figures I'll actually end up getting, but here's what I hope to see outside of the predictable main cast (Vader, Chewie, etc.) and obvious others (Stormtroopers, Boba Fett, etc.).

Grand Moff Tarkin
Han in Carbonite block (at this scale should be electronic)
Royal Guard
Greedo
Snowtrooper
Biker Scout
Any other Imperial (Drivers, Pilots, Troopers, Gunners, chokefodder Officers)
Rebel Fleet Trooper
Wedge
Biggs
R5-D4
The Bounty Hunters (Bossk, IG-88, etc.)
Any Skiff guards
