Well I was sent a small clip of "Candy Shop". Big bass sound and you can tell its JT-Timbaland. Her voice seemed too high-pitched for me, but the sound quality of the clip was not the best. That track however is not scheduled to be the first released single.
Being a "Madonna faithful", I am highly anticipating this project, though. It probably wont top Confessions for me, as that was such a straight-up "electronic" dance record, but still.
It's projected for Oct 29th right now with yet another tour in '08. I need to start my "tour fund jar"
