Unfortunately there are subtle paint detail differences in Vader and Rieekan. I passed on openers of these two this morning and wonder if it was a mistake for completeness sake.
Vader's shoulder armour uses a much darker grey color instead of the loud silver from the 500th release. I can't tell for sure if the cape is actually different but it looked tightly connected to my eyes as well.
Rieeken is odd. There are no changes but the colors of the paint are definitely different. The shoulder brown is darker on the new one, and the fleshtone of the head plastic is lighter. The glove paint is also more tan than the Deluxe version.
All very pointless, but it means I need to pick them up if I want to take loose pictures of these guys. They're not the same as the earlier releases, technically. Plus, since the stands all are labeled specifically for the character, technically a loose collection wouldn't be complete without opening up these repacks... Colman and I are screwed.
I put up some shots of the figures in this wave here in the Image Database TSC section
