Here's a bigger and clearer photo of the new three-pack so you can get a better look at each figure.
R5: repack of the 2006 figure.
DSD: repaint of the popular BAD mold.
Unlike a lot of other Hasbro SW product, the Target-exclusive sets seem to be ordered and shipped in decent numbers so finding this one shouldn't be too terribly difficult for most collectors so long as they have a Target nearby. Due to the presence of the BAD Death Star Droid and the brand new Gonk I do expect it to sell better than most of the previous Target sets, though.
