I honestly think that the 501st "find" over at GH was a hoax. The photo looks like it's been doctored all to hell, there is no receipt for proof, and we are supposed to believe that the 501st was the only figure from that assortment hanging around at all. If it is legit, I'll retract my doubts, but with nobody else seeing these at all, I call shenanigans.
The local Target apparently got one case of the 57-63 wave this morning. Another local guy got the Bly, Gree, Miin, and Passel a few hours before I found the Guard, Neimoidian, and Wookiee (aka "Pegwarmer Redux") this afternoon; all the other figures from the case (2 Vaders, 1 R2, 1 AT-RT Driver, and 1 Pilot Obi-Wan) were still hanging around as well.
