That true, but there was one thing bothering me. I know Yoda was younger and all, but he looked it. Episode II is only what, fourt or so years before ESB? When your an 800-and-something year old alien, I doubt fourty years will really make a difference on how you look. The new Yoda just looked too young to me. I also think that fans would have been upset if they hadn't used a CG Yoda. As you said, things change, but it's how he looked that sort of gets me.
