I believe I saw GL saying something about changes he will make on the ROTS dvd, also, in one of the docs, you see a slip of yoda in E1, but's it's not the puppet, it's a cg Yoga, probably for the new dvd release. (Hope I'm not going on about things everyone knows)
p.s. keep your yasims to yourself George, and take Rick McCallim's ass kissing down a notch.
