@meatwadf: In the Rebels Visual Guide it says that the clones were decommissioned and patriotic Imperial citizens were recruited and placed into academies. Also, in Rebels, at the Imperial Academy on Lothal one of the Stormtroopers in training is black sooooo... There ya go.
Greatest thing about this was when Ezra senses Kanan. Wow. Goosebumps! So excited for this show! It has so much going for it! Dave Filoni and co. from The Clone Wars, plus Greg Weisman, and Simon Kinberg too! This series has so much potential, I'm ready to see it live up to it.
@amazingwebhead: In the Rebels Visual Guide it says that all of the clones have been replaced by normal born people who attend Imperial Academies. So hopefully we'll get to see why that happened and maybe the clones will want to strike back! (Captain Rex *cough cough*)
