I wonder if they'll dirty up the armor for the Stormie Luke and Han, to emulate the trash compactor scene. I want them clean for other scenes, but then they won't look much different from the regular stormies. Maybe they'll have some nice exclusive pack-ins like a better scaled Mouse droid or a piece of DS control panel. I'm really hoping for the Praji or similarly-dressed black outfit Imperial officer in the wave, too.
Thinking more about the Ben, I realized that if they go the soft-goods route, they MUST use the fabric from Hermi Odle and not the typical cloak material. Hermi's type responds perfectly to the water treatment and holds its shape, giving the appearance of weight. Otherwise, I hope they give us the molded cloak version like that from the Spirit Ben of a couple years ago.
