While Guitar Hero has been a hit and continues to sell most incredibly, it seems that Activision is not resting on its laurels and are putting their plan together to expand the Hero franchise, with the registration of the trademark DJ Hero. The trademark relates to “”…computer game software and related instruction manual sold together as a unit; interactive video game programs; computer game discs; downloadable software for use in connection with computer games; video game controllers; interactive video game comprised of a CD or DVD sold as a unit with a video game controller.”” What video game controller it is referring to remains to be seen.
