Yes, Norah Jones "Come Away With Me" will be released on Hybrid SACD (SACD and redbook CD layers) on the Blue Note label on April 22, 2003. It will be release # 7243-541747-2. Of course that information is tentative and I also assume no responsibility for its accuracy.
I am also eagerly awaiting this release. I just picked up the two Diana Krall SACDs too ("Look of Love" and "When I Look in Your Eyes") and they sound pretty good so far.
