The Vader looks like the same sculpt as the Emperor's Wrath version, just with a new mechanical piece running through the arm. My question is, do we really think he comes with the stuff pictured, or is that just some parts of the figure disassembled? The little mechanical piece next to him looks to be the same one inside his right arm, and I don't know why a Vader would come with a skull besides the one inside his helmet. So he can do a Scorpion fatality, perhaps?
I'd be surprised if Luke's body is different under that poncho, but either way, this is a kitbash that makes sense and that I've wanted for a while. The rebel guy looks pretty good and should fit in with the Endor soldiers I already have, while being an improvement over them in the articulation department.
