Derek, yes, it appears that June 10th is the day...for now. I wouldn't camp out at your local store the night before if I were you based on the way things have gone with this title.
Some people here and on Audio Asylum claimed to have the SACD already. I don't know how that can be. Perhaps they had the CD and didn't know it.
Thanks for sharing the comments on the surround-sound mix. If that's true, it will be a real treat. A club-like mix suits the album perfectly. A whiz-bang, in-your-face mix would be a disaster. Completely inappropriate.
