Looking at the photos and then looking at the original figures on which they are based (no pun intended), it's fairly apparent that these are practically straight rehashes, with minor sculpting changes on Han and the Clone.
The Han is the exact same pose and the exact same body as the previously (un)available Stormtrooper from earlier this year. The only difference is the head, but at least they did a removable helmet. The base, however, looks completely new, as is the tentacle (although it wouldn't surprise me if they went back to the Fett's Sarlaac and used one of those; I just can't tell from the photos).
The Clone is the exact same mold as the AOTC Clone(s), but with a new head and a new blaster, and obviously a new paintjob. Again, the base is completely new, and Clones are popular enough (and the sculpt is good enough) for me to not be upset at all about this one.
Both of these will probably fly off the shelves, as even though they are rehashes, they are different and unique enough that they will still look great displayed with the others. Chewbacca, however...
It's the same figure as the one previously released that nearly everyone disliked (I didn't think it was *that* bad myself). The main gripe most people I know had with it was that "base" which was just a blob of green and instead of doing something interesting with it this time around, we get the same blob, only in tan. His hand was already molded to look like it could hold something, so they just slapped that Wookiee totem pole shield in it and gave him a new gun, which looks fairly awkward in the photos.
I just hope that these figs don't kill the line.
I don't think they will, as I think the Han and Clone will sell really well, but Chewie is going to be around for a long, long time I fear.
