The edit will be all the better for it, anniversaries be damned. In fact, I don't recall good things happening on any Star Wars anniversary year. In 1997 we got the lousy SEs. In 1987 we got a Hamilton Collectors Plate collection and a poster (not bad, but kinda lackluster too). In 1992 (15th), we got a few reprinted posters. In 2002 (25th), we got Attack of the Clones - bleck!!!! I almost went blind that day.
It bodes WELL that the Revisited edit is not taking place on an anniversary year.
