Mace Windu - He appears to be an entirely new sculpt.
Obi-Wan Kenobi - Reissue of the Pilot figure but with a new head that accommodates the aqua-breather accessory. Also comes with a new version of the Magnaguard pike and Grievous's blaster-- but no lightsaber?
Galactic Marine - The kids are gonna love this one!! Snowtrooper in new grape flavour!
Artoo-Detoo - Better than previous attempts on the rocket-Artoos but the paint deco leaves something to be desired.
Mustafar Lava Miner - Freaky!!!!! I love it!!!
Airborne Trooper - The sculpt is a little soft but it's still good nonetheless!!
Super Battle Droid - It looks like a new sculpt (in hopefully sturdier plastic) and it has pivoting elbow joints so it can grab or fire! Speaking of fire, it's also got some odd fire deco.
McQuarrie Concept Stormtrooper - Same trooper... new deco.
I'm likely to pass on the Obi-Wan and the McQuarrie Trooper. I may pick up a Super Battle Droid, a Mace and an Artoo but the rest of them are definites!!!!
