With Star Ware you just about have to have Bespin. If you have Bespin you just have to have Lando. Well, Imperial Assault is headed to Bespin. So that means Imperial Assault is going to have a Lando. That's what we get a preview of today (they couldn't put all the Star Wars stuff back on the 4th).
As is customary for these expansion packs, there's more than just a miniature to replace the cardboard token from the base game. There's a new scenario, as well as new equipment and abilities that you can use in any game of Imperial Assault (not just ones using Lando).
