If you thought Activision's milking of the Guitar Hero franchise was ridiculous when they announced the Aerosmith version of the game, wait until you hear this: Joystiq is reporting that Guitar Hero: Metallica is in the works and will hit store shelves before the first quarter of 2009.

Details such as whether or not the game will use the new peripherals coming with Guitar Hero World Tour haven't been announced, but you can be sure that this certainly isn't the last of the band-specific Guitar Hero titles, provided that this and the Aerosmith game don't flop at retail.
