Well the Prequels need every possible improvement they can get ;-)

So it is nice to have this edit as a foundation for new versions of the story that was before the OT ...

If the whole lightsaber debate has a deeper meaning, not just "we didn't see color X in the OT" - saying the colors have a meaning in tradition or aspect of the Force, then go with it - for me it isn't that of a problem, because we had only blue and red until Luke built his green one in ROTJ (and if we go back to concept art, the lightsabers would have been all white!)

My only gripe with the "Clone Wars" is, that we don't see some "old" ships, as with the Y-Wings, those need to be inserted at some point!
