I just saw the R2-D2 action figure variant cover on the Previews website for upcoming variants. I actually think this is the best variant so far.
Hopefully the action figure variant for Star Wars #7 ends up being a Jawa. My fear of a Jawa variant - is that there would be two of them. A normal cloth cape Jawa and an ultra-exclusive Jawa variant cover with a vinyl cape though.
Of interest, following the Marvel Panel at Star Wars Celebration Anaheim, I mentioned that it would be really cool to have action figure variants of the three new popular characters introduced in Darth Vader #3 (i.e. Dr. Aphra, Triple Zero, and BT-1). However, because these characters don't yet have action figures in the real world, this might be stretching it.
