I scored most of this wave while out in New England this past week - just missing Gree at this time. Here's my 2 cents on these figures...
Vader: Great to see the Evo ROTS Anakin in circulation on a basic card. They've re-done the paint job to bring out some details, especially in the head. They did however paint the right glove arm brown instead of black. The hip articulation works really nice on this one and I'm definitely going to want to nab another when I get the opportunity. Of course I would have liked to seen ball-jointed elbows, but we all know Hasbro will get to that on the next refresh of this figure - damn them for knowing we'll buy it!
Obi-Wan: Whereas the new hips work well for Anakin, they don't as much for Obi-Wan. For starters the cloth skirt actually restricts some of the movement in my tests (you know, extensive playing with the toy

) and the design gives the impression that Obi-Wan is birthing. Add to that an even wider stance than the original Pilot figure and the hip articulation is a bit of a downer here. The head looks ok, but it appears I have a bad one (I'm not the only one from what I've been reading) as the hole in the head for the ball joint is not big enough to accomodate the neck joint. A little fixing will have to be done on my part and no doubt Hasbro will fix this as they did the comic pack Mara last year.
Po Nudo: A nice sculpt, the head looks pretty vicious. He's loaded in the arm articulation but the design of his cuffs at the end of his arm restrict the hand movement. The robes prevent access to the legs, but it's not such a big deal for this type of figure.
2-1B: The sculpt on this one is amazing and he's full to the brim with articulation. The details really stand out nicely, it's a well done figure. The size may be an issue for some, but it's easy to think that this particular model is of a shorter height than say the 2-1B we saw in Empire. A cool droid for sure.
Panning Droid: The detail is ok on this guy, unfortunately he suffers from Hasbro's soft plastic and the legs/arms have already warped. I don't see how the droid itself could stand long if you put Anakin on as intended. The platform is well done, I like the addition of the lava form under it. It's been designed to be modular so if you want to do an extended platform for the duel it's definitely doable.
Tri-Droid: Again we have an issue with soft plastic and an odd design. I couldn't figure out at first how to attach the legs and when I finally did they just didn't snap into place properly. The feet on the legs are made of the typical crappy plastic so it won't be long until this guy is tipped over. With that said, the detail is well done, the sculpt gives this one promise and could definitely fill out the Seperatist droid ranks as long as you don't have an issue with the feet.
Kashyyyk Trooper: The lame one of the bunch in my opinion. I know this is supposed to be a more accurate sculpt, but I prefer the repainted VTAC Biker Scout and as such I'm only going to stick to this one figure. There's nothing really new to this guy and the paint job pretty much sucks, I think the biggest eye sore though has to be the huge backpack he has, it just does not look good.
I did get to see Gree as my buddy picked it up and that does appear to be a good figure. An all new sculpt with the suspenders added for realism and the new hip and wrist articlulation make for a nice fun bonus.
