Although Smuggler Lando is really tempting, I'm going to pass on this entire wave:
4-LOM and Torture Rack with Han pack-in are decent enough but I don't feel much compulsion to buy them.
General McQuarrie (Hoth Trooper) is quite cool, but I don't have a lot of Hoth figures so he'd be stuck hanging with POTF2 Hothtrooper and Pilot Luke.
The Concept Snowtrooper has the same problem, and he looks too weird to file under "normal" figures anyway.
Bring on Waves 5 and 7!
