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)
Any other Imperial (Drivers, Pilots, Troopers, Gunners, chokefodder Officers)
Rebel Fleet Trooper
The Bounty Hunters (Bossk, IG-88, etc.)
Any Skiff guards
