The following trailer shows some interesting new gameplay elements in the Harry Potter universe.  The magical brewing looks almost like the class chemistry gameplay on Bully, but considering how intuitive the magic wand controls worked on the previous installment of the Harry Potter series, I assume that the controls should be more in-depth.  This game is scheduled for release on November 2008 to coincide with the theatrical release of Harry Potter and the Half Blood Prince, and will be available for the Wii, Xbox 360, PS3, Nintendo DS, PSP, Mac OS X and Windows platforms.
