Amazon has put up the Harry Potter and the Deathly Hallows soundtrack and states that the release date is November 16th, 3 days before the film premieres!  There is still no cover art shown, but hopefully it will be released soon!

The soundtrack was composed by Alexandre Desplat who has done such films as Julie & Julia, Fantastic Mr Fox, The Curious Case of Benjamin Button, Coco Before Chanel and The Golden Compass.

This date has not been officially confirmed by WB, but it seems about right to me.  Most of the soundtracks have come out a few days before the films in the past.
