Did I miss something? I was bumming around on imdb.com and was looking through the credits of Munich. Low and behold, Ben Burtt is listed as sound designer and sound editor. I know he left Lucasfilm / Skywalker right after Sith was released. I never read or heard anything about him going back. He's even listed as sound designer under staff on Skywalker Sounds' web site - www.skysound.com. I was a little surprised to see that.
