Nothing too new to report, and I'm not sure how this was missed until now, but Hasbro's Q&A round-up has a picture of a new Galen Marek from the upcoming sets. It's very Mandalorian-riffic (using Evolutions Jango's torso and arms, it seems) and has a new, more accurate head sculpt. Was this costume in the original game? If not, it could be a preview for the second one (or maybe it's in Ultimate Sith Edition - I have no idea).
The page also has the new Juno Eclipse, but we've already seen that, so there you go.
