Guitar Hero Maker Files 'Sing Hero' Trademark

Activision, which publishes the popular Guitar Hero series of music video games and develops them through its internal studios, has filed a trademark for "Sing Hero," prompting speculation that the company may be prepping a dedicated karaoke game.

While the Guitar Hero franchise added vocals and drums to its repertoire with last fall's Guitar Hero World Tour, Activision has promised a "major re-stage" of the Guitar Hero franchise with "all new differentiated Guitar Hero products" in the second half of 2009.

That includes at least one more Guitar Hero game, DJ Hero, and, if rumors are to be believed, a dedicated Van Halen music game and something called Band Hero.

Don't forget, Activision plans to triple the amount of Guitar Hero releases by 2010. Three more Guitar Hero games are due out by the end of June, including Guitar Hero Metallica, Guitar Hero Greatest Hits, and Guitar Hero On Tour: Modern Hits.
