An interesting one as there's barely any troopers they can do to pad out the releases. I'd say next to no chance for the DS Trooper, AT-ST Driver etc. due to head sculpts. It's way too early for a Scout Trooper re-release. Maybe a Stormtrooper re-release.
I have a horrible feeling they won't touch Jabba's Palace (there is an exception). I doubt they'll do Jabba or Slave Leia, so that doesn't bode well for Gamorreans or Bib Fortuna.
My predictions are:
*Boba Fett (re-release)
*Darth Vader (w. Sebastian Shaw hs)
*Emperor (re-release, but only as part of a 2-pack w. Vader)
*Endor Luke/ROTJ Luke (w. updated non-grimacing hs, and possibly speeder bike)
*Boushh
*Han & Chewie (I actually think this will happen before the ESB version)
*Ewok Village Leia (w. 2-pack option inc. Ewok)
*C-3PO (so that you can accessorise him for any of the OT films)
