guitar_hero_logo In the first of quite a few Guitar Hero posts today, Activision Blizzard let it be known that it will triple the amount of Guitar Hero titles and content it offers by 2010. This was revealed by company CEO Mike Griffith at its Analyst Day.

Griffith noted that the expansion refers to both retail titles as well as downloadable content for the series. In fact, Activision plans on doubling the amount of Guitar Hero releases in 2009. The sudden expansion will be accomplished by bringing in more developers and more hardware suppliers.

Guitar Hero World Tour, usually referred to as Guitar Hero 4, will be released on PS2, PS3, Xbox 360 and Wii on October 26.
