Well, the countdown may now officially commence. This is from the OfficialStar Wars website

The circle will at last be complete when Star Wars: Episode III is released to theaters in the United States and Canada, with a near-simultaneous release around the world, on Thursday, May 19, 2005. In Japan, Episode III will be released in July, the traditional month for Star Wars premieres.

And yes, I must sadly say that I will probably stand in line for tickets again. Will I never learn?
