Blizzard Entertainment will enclose a soundtrack with the collector's edition of the expansion World of Warcraft: Mists of Pandaria, set for release on September 25. Veteran Blizzard musicians Russell Brower, Derek Duke, and Neal Acree were joined by some surprising new faces on the project, namely documentary/film composer Sam Cardon and Guild Wars' composer Jeremy Soule. A digital soundtrack release is likely, but unconfirmed.
