Has anyone thought about how the music and themes will fit into Episode IV? The Imperial March did not show up until Episode V so why would we see it in Episode II and III? I think that to have all the films use the Imperial March except IV seems a bit odd. So maybe use the Empire's theme from ANH for Episode II and III to provide some consistancy. The only other option is to rescore parts of ANH with the Imperial March melody and I can hear the purists freaking out already.
