Some thoughts...
-Kit Fisto's apprentice? Pretty cool...
-Kit Fisto's Voice? Matches his "ah!" he lets out in Palp's office when he's cut down, which I think is cool they made sure to try and match it.
-Armored Y-Wings... Very cool, and will we ever see a (to-scale) toy? If so I think I'd go nutty over that.
-Clone armament... Very cool seeing the mini-gun dusted off and brought out of storage from the 2D toon. If I may suggest, head on over to Marauder Inc. and buy their mini-gun accessory for your Clones NOW. It rocks socks.
-Yoda... Cool, badass as always, fights with his mind more than a weapon, and his talkign with the Clones seems very cool, like he truly wants to see them become more than they are. It's kind of sad when you think about it.
-Grievous... Way cooler than ROTS, and way more tough like he should've been in ROTS.
I loved the film, so maybe I'm biased, but the preview tonight has me excited for something to watch every week, finally.
