A new Guitar Hero DS game is to be expected in 2009, along with another Guitar Hero game for consoles, which Activision said will be announced at a later date.
Guitar Hero as a franchise will receive a "major re-staging" in the fourth quarter of 2009, the company said.
Guitar Hero has an install base of 32 million worldwide, the firm said, and outsold Rock Band four-to-one in the US despite supply constraints.
GH was the number one selling franchise in Europe with a 122 percent increase in holiday sales.
Activison said the genre is generally robust, and consumers will be accommodated by the release of different music genres to its games.
The company expects the music kit game install base to grow by 53 million units in the coming year, and new users to franchise have broadened the demographic and want more variety.
To help the company accomplish their growth in the Guitar Hero franchise, in Europe it will include more Euro bands.
The company said the release of DJ Hero will be innovative and take franchise in new direction.
In addition, a greatest hits compilation will be released, and with Metallica being inducted into the Rock and Roll Hall of Fame, this will help the sales of the upcoming Guitar Hero: Metallica, which is set for a March release. The PS2 version will arrive a bit later on.
