For me right now, the Endor Commando is the most interesting of the lot... Hasbro super articulated his legs if I'm not mistaken. I think I see ankle joint lines there, and ball/socket knees.
While it's not totally new, the waistcoat looks like it's shortened slightly at the shoulders and may leave for better poseability at the arms. The legs look like a VAST improvement but I'm gonna wait to see one loose before I judge it completely because they are still spread apart wide. If it is articulated that shouldn't be a problem but only if the knees and ankles are poseable. Otherwise it's gonna have a wide leg stance irregardless.
The head looks like a Lando head to me... To be honest I'd have preferred them repainting (different hair color, maybe some painted on stubble) the two heads the Saga 02 figure had, but still an African American head is cool too, I just think that's a Lando head slapped on there.
The new belt looks rocking on it though. Very cool to get a holster for a RFT pistol. I hope he comes with the rifle as well though as the Endor Soldiers weren't seen with anything but the rifle. As a kitbash with only SOME new toolings I think that's fair to ask.
Right now that's the most exciting figure for me... An army builder, and what may potentially be the best Rebel Soldier army builder to-date... The only current disappointment I have is the lack of new arms. It'd have been nice to get some ball/socket elbows on the soldier, but overall that body wasn't bad, it was always the legs that killed the figure for me so this makes me glad... I've even customed up a couple troopers using better legs and that same torso just because the legs always killed that figure for me.
