well, first of all it doesnt take place in between ANH and ESB. It takes place between SITH and ANH...and according to folks I know that are involved Boba Fett will have a significant part. Whether we see Ep3 clones, TKs or (probably) something in between remains to be seen. Msot of teh writers and creative folks are italian and apparently Lucas is going for a sergio leone/spaghetti western feel. Lucas has also brought HBOs 'DEADWOOD' up several times as a heavy influence.
