It is all but official that the 2004 DVDs won't be exactly the same as the 1997 Special Editions. The digital bits has reliable sources that say this. Not just fan rumors actually industry sources. Though I doubt the changes will be to great. Like Jay said probably just more line deletion and saber work. Stuff that should have been done in 1997. There will be alot more changes coming in 2007 for the 30th aniversery Ultimate Editions.
