I saw this wave today, except for Leia, Nikto and the Ewoks, and only bought the Klaatu guy. I might pick up the Prune Face guy if I see him around again. I thought the Luke looked pretty bad; the sandstorm Luke without all the extra gear is still a better representation, IMHO.
The Rancor Keeper guy is a worthless resculpt; he doesn't look that much better than the POTF2 version (although I'm sure the added articulation is a bonus for a guy who doesn't really do anything but cry).
The biggest disappointment for me, though, is Nein Numb. I don't want a B-Wing pilot Nein Numb, I want the one with the vest; the way the vintage and POTF2 versions looked. So close, yet so far.
The Klaatu guy is fantastic, though. Work of art.
