This whole business reminds me of certain aspects of George Orwell's "1984". Where the government have to constantly alter the past in order to ensure that it tallys with the current state of affairs! Perhaps this is a lesson for the future..if you insist on starting a visual saga half way through and then continue to tell that story from the beginning, some of the "later" images will need to change to tally with fresh information.
Yes, it sucks but there are worse things to worry about.
Just like Big Brother, George Lucas loves you..and he is doing all this to tell a simple story the best way he can.
You'll thank him for it one day...............
