An RS forum member in the Far East opened one of these sets up (Jedi Council set w/ Mace, Oppo, and Piell) and has given a nice little review of it
here.Removable chairs, no lightsabers, some good and bad articulation, non-removable hologram, slot for a cardboard backdrop (which didn't sound like it was included), and a pair of hidden arms on Oppo...
I saw the two connected Jedi Council sets (loose) at the Comic Con this weekend, and must say that they look very cool when put together with all 6 Jedi present. Hasbro better keep these sets up, and give us some more so we can complete the full council! Of course, since a couple of the figures aren't articulated to be able to sit down in a chair, that presents a slight problem to us non-customizing folks...
One thing that didn't look good, which I'm hoping was just because it was only a mock up sample for the show, was Mace's knee(s). The color of his knee joint (which is only visible when he is sitting), was brown - whereas the rest of his legs were white. Looked pretty bad (think Greedo's off-colored knee pins), but like I said, hopefully it wasn't the finished product. Can't really tell from the RS pix if this problem is still present though...
