Hot off the heels of the success of Guitar Hero III, a filing from February 8, found by Trademork reveals Activision may be adding to the Hero franchise with DJ Hero. Activision hasn't dropped any hints to what it means but we assume that it will be in line with Beatmania, another Konami idea that didn't get the right push Stateside. We're completely optimistic for new rhythm games and we hope this one pans out. How else will be get to play the ninth annual release of DJ Hero titled, DJ Hero IX: Oakenfold - and if other ideas sell we just might see that happen. Now, we don't know what the controller would look like but Activision had better give Aaron Stillman a call for a few tips.
