Back in February, Activision revealed it has two new disc-based expansions up its sleeve, one of which was soon after announced as Guitar Hero: Aerosmith, the series’ first band-centric installment. As we get near Aerosmith’s late June release, the second of the two band-based Guitar Hero iterations has been unearthed via the company’s recent SEC filing – Guitar Hero: Metallica.

Activision’s report clearly states Guitar Hero: Metallica as one of its upcoming new installments in the series:

“In fiscal 2009, we plan to publish Guitar Hero: On Tour for the NDS; Guitar Hero: Aerosmith, Guitar Hero: Metallica, and Guitar Hero IV across multiple platforms.”

For those not in the know, Activision’s fiscal year ends on March 31, 2009, which means that the Metallica-based Guitar Hero game should be out by the end of March 2009, very likely sometime after the release of Guitar Hero: World Tour this Fall.

Does Metallica sound like a good choice, or were you expecting some other band to frontline the new expansion?
