Following in the footsteps of Aerosmith, the no-longer-technophobic dudes of Metallica have just announced that they too will be partnering with Activision to release an (almost) all-Metallica version of Guitar Hero: World Tour sometime in the first half of 2009. The track list has yet to be nailed down, but the Über-geeks over at 1UP got a sneak peek at some of the songs and it looks to be a rager. Don't be caught unprepared: It's best to follow Vulture's lead and start building up the calluses on your fingers now. [Rolling Stone]
