Dre's been working real hard on a few albums for other artists (busta, etc.) so that's one reason why it keeps getting pushed back.
He had already come up with 50+ instrumentals and hot tracks for it, and scrapping all of them except his absolute favorites. So it's going to be sick.
There was about 1 or 2 tracks that got leaked that may or may not even end up on detox, but those might be hard to find on limewire.
The stuff on limewire for the most part are way old tracks or just alltogether fake.
Dre really wants to do something groundbreaking with the album and willing to redo it all a million times over if that's what it takes.
So I'm hoping it's going to be pretty damn good.
