Thanks to www.rebelscum.com for the info, this is a pretty sweet set:
Diamond Comics announced today that they will be carrying a 7-pack of bounty hunters from The Empire Strikes Back. Available in OTC packaging the set will include Boba Fett, Dengar, Zuckuss, 4-LOM, IG-88 and Bossk plus the chief negotiator - Darth Vader. The precise arrival date is unknown but sources have indicated that it will be out before the end of the year.
This looks like a great set, and a great way to get all the bounty hunters that were missed prehaps earlier. Again thanks to rebelscum for this news!
