I found an auction on Ebay that showed carded pictures of Zam Wesell and CloneTrooper as well as Jango. They are on the green POTJ card, so I guess we have confirmation that the four charecters pictured on the back of the card are the preview asstortment. No pictures of R3-T7 yet, but if I find them, I'll post. I'm attaching images of the carded Zam and CloneTrooper figures, since we have already seen the Jango.
MTFBWY and HH!!
