Looking even further out, we're exploring new models, like an annual pass subscription where players can subscribe and get a certain number of songs downloadable each month.

No further details, such as a price or a start date for such a program, were made available. The plan would, however, be just part of Activision's plan to "monetize" the Guitar Hero series.

"We've learned that the consumer still has an insatiable appetite for more," said Griffith. "Consumers have downloaded over 20 million individual songs for the franchise, and they still tell us they want more," he added.

"In fact, the Guitar Hero: Aerosmith game delivered 10x the revenue compared to Aerosmith's most recently released CD in 2004, when comparing equivalent launch periods," Griffith continued. Most of the revenue from the game, of course, went in Activision's direction instead of Aerosmith's.
