Potterish has been told by Warner Brothers Brazil that John Williams will score Part 2.  This has not been confirmed through my sources, but Mugglenet, Leaky and some other sites agree that it seems pretty credible.  But it is still a rumour until WB releases the information everywhere.

John Williams hasn’t done a score for a Potter film since Prisoner of Azkaban, and I personally hope he is coming back for Deathly Hallows Part 2!  As most of you will remember, Alexandre Desplat is working on the score for Deathly Hallows, Part 1.
