According to CVG Activision have filed a trademark for a game titled "DJ Hero".
The trademark reads:
"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."
Let's hope it comes packaged with the new Pioneer CDJ-400 for just like £50. I can dream can't I?
