I'm working my way thru ESB at the moment, up to the Luke/Vader duel. The first two shots look like 2004 changes to me, curious why none of the duel lightsabers are in the Comparison guide. Was a conclusion drawn about them or no one's gotten to it yet?
There's turning out to be a higher percentage of shots affected for ESB then SW. But almost 95% are minor (V1) things.
