I got my cases last night and cracked them open so here is a quick review:
Luke: Much better than expected. The head sculpt is really nice as is the articulation. If the legs were further apart it would allow for much better posing. They also painted the saber differently to better reflect Luke's (It's ROTS Obi-Wans repainted). Chest plate swap is also integrated well.
Ewoks: Superb as always. New heads, weapons and hoods. You can easily retire your POTJ Paploo. The new one is very reminiscent of the vintage and more accurate to the movie.
Slave Leia: Home run, this figure is great! While to some the articulation may look weird to some, they balanced it out by making her more busty and curvy. While the POTJ one still looks good and more real this one is about as good as it gets to have your cake and eat it too.
Nikto: A really long overdue character and worth the wait. My only complaints are the hood falls off too easily, the gun is too small and the skin color is on the darker side. I really dig him none the less and he is not lacking in articulation. Sailbarge canon is really cool, hopefully one day it will have a home.
Rancor Keeper: For an old school pegwarmer this figure sure makes up for the past sins of the old one. He is fat, dirty and super articulated. Likeness is dead on and he will make a fine companion to the Target Rancor. Superb detailing too.
Klaatu - A perfect companion for a fat slob to cry one. Like Nikto his hood comes off easily but is very well done. The biggest flay are the knees as they do not have enough room to properly move even though they are articulated. Neverthe less he is a perfect addition to Jabba's Ranks.
Nien Nunb: A perfectly fine repaint with a much darker tone to the red flight suit. I wish they would be more consistent with this because the X-Wing pilots & greay imp officers suffer from this same problem. He is much pinker than Ten Nunb.
Pruneface: I was never a big fan of these ET wannabes but the figure is really nice. The cloak material looks really good and should be a preview for General Lando's eventual upgrade. I got rid of my POTF2 version with the pirate patch but you can see this guy has a good chance to be reused to make another Dressillian. The only real flaw I see is the paint wipe on the paints, it's a little sloppy.
The two new astromech droids are nice, I like the Dexter Diner one better.
For the exception of the Scouttrooper The rest of the case are repacks that have nothing to do with ROTJ. I get the fact they want more variety but one repack choice is very redundant - Jango Fett. He was just rereleased in the AOTC wave and you will get him again in the Target pack so stuffing him this case seems like real overkill. EP2 Obi-Wan makes some sense as he was short lived. FYI - They updated his saber with the flare.
I found this wave more enjoyable than the TPM wave as it had more characters with key upgrades to old ones.
