TOP 3 Reasons:
Lucas is actually considering episodes 7, 8, 9. That means more changes to come to the OT. Maybe removing the Corisant celebration?
2007=30th Anniversary: Bluray (HDDVD?) big momma jomma set is in the works. Can you say all 6 movies reworked, again... Maybe we can hope for original versions on these, but my breathe isn't held.
I LOVE the original versions. I saw the SE's in the theater (yes all 3), and almost cried.
