Meh, IMO there shouldn't even be Stormtroopers of any fashion 30 years after the fall of the Empire. (That'd be like having Nazis in full regalia running around in the 70's. Evil Empires disappear quickly) I kinda wish they would go in a different direction, like a Sith Army or something.
I didn't realize how much spoilerage I had missed already. Luke is now in captivity? His lightsaber floating through space is the opening shot? Huh???
Given that Disney doesn't care what your EU books say, shouldn't we wait to see the movie before we declare that the Empire's been gone for 30 years?
