Activision has been hitting it big with the Guitar Hero franchise, and we know it's looking to expand what it can do with the series. I don't think anyone is going to be surprised by this next bit of news: on February 8, Activision filed to trademark the name DJ Hero.
The trademark refers 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." It looks like your guitar is going to get a friend.
This isn't a new idea; Beatmania has been around for quite a while. Of course, Guitar Hero is simply a refined version of Guitar Freaks, so this won't be the first time Red Octane and Activision mine an area Konami has had some success in. There is no other information at this time, but it shouldn't be that difficult to adjust the Guitar Hero formula to a DJ set up.
We'll be watching for more information, but it's safe to say that this is the last Hero game we'll be hearing about.
