the vinyl has been a great direction IMO, and getting Lando (vinyl), bespin Leia (vinyl), Lobot, and another shot at shiny 3-PO in parts would be nice. Plus the Bespin guard and Ugnaught are still waiting for their bricky release. I have a feeling Luke would end up in the wave, maybe in a little rougher shape than the series 4 release. I don't know what would make a good BAF though- the circular walkway where Vader tells Luke about that two faced Obi-Wan would be pretty cool, but seems pretty unlikely.
I struggled with that too. Not a very interesting piece. They could do the Freezing Chamber or the Han Torture chair too, but meh...kinda boring. I'd love a Cloud Car or little Slave-I, but that seems too big. They could stray to Hoth and give us a Taun Taun...it's not like we ever saw a probe droid on the Death Star.
