This morning, Amazon sent out the following email to people who had pre-ordered one of the Star Wars Blu-Ray sets:
We have good news! One of your pre-ordered items is now eligible for release date delivery and has been upgraded at no additional charge. Your new delivery estimate is:
Mark Hamill, et al "Star Wars: The Complete Saga (Episodes I-VI) [Blu-ray]" Estimated arrival date: September 27 2011
Release date delivery on September 27th sounds a lot like a September 27th release to me! Amazon's three product pages for the sets now list this date as well.
