Start saving! U2.com has just posted a link listing the various formats that will be available on October 31 in the U.K. and on November 1 in the U.S. Five physical editions will be available alongside digital only editions. The most difficult decision now is which format to buy!
The most expensive is the Uber Deluxe Edition, costing around $$450. It's described as
"A limited numbered Uber Deluxe Edition is a magnetic puzzle tiled box which will contain: 6 CDs including the original Achtung Baby album, the follow-up album, Zooropa, B-sides, remixes and re-workings of previously unheard material recorded during the Achtung Baby sessions. 4 DVDs including From The Sky Down, Zoo TV:Live From Sydney, all the videos from Achtung Baby plus bonus material. There will also be the Achtung Baby double vinyl album plus 5 clear 7" vinyl singles in their original sleeves, 16 art prints taken from the original album sleeve, an 84-page hardback book, a copy of Propaganda magazine, 4 badges, a sticker sheet, and a pair of Bono’s trademark 'The Fly' sunglasses."
This page on the Universal Music online store includes a track list that appears to still be a work-in-progress.
