the way i see it the Marvel packs just come with cool background characters.
Umm... Luke, Han, R2, Chewie, Obiwanx2 (PREQUEL), Anakin, Leia, Vader x2 , Fett, Tarkin, Bail..... what great background characters they were!
Using comic adaptations of the movies should not be considered EU for this project. This is GREAT opportunity to give us something new and to promote the Expanded Universe which contains so many great NON-MOVIE characters they could make for us but they're too cheap/lazy to do it. Sure.. there ARE sets within the comic packs that fit my view of the EU but I feel that opportunity is wasted on characters we already have a bazillion of (cut it out with the stormtroopers in these!).
