It is posted on Stephenie Meyers' site www.stepheniemeyer.com the following:
Due to overwhelming and unprecedented demand, Chop Shop/Atlantic Records have announced a new release date for THE TWILIGHT SAGA: NEW MOON ORIGINAL MOTION PICTURE SOUNDTRACK. By far the most anticipated soundtrack of the year, the compilation will now be released this Friday, October 16th, four days earlier than originally scheduled! If you have pre-ordered the album, you can expect it to arrive on that date or shortly afterwards.
In addition, we would like to exclusively announce that in the physical CDs, the booklet folds out into a poster! The image is below. Make sure to head out on Friday to get your copy of THE TWILIGHT SAGA: NEW MOON Soundtrack!
