Yup, Activision is no longer making Guitar Hero, or it's sub-games like DJ hero. The official story is that interest in the music genre is declining and Guitar Hero is no longer profitable, so their just going to focus on Call of Duty instead. Of course the real reason why Guitar Hero isn't profitable anymore is because Rock Band is simply better, and they only release one Rock Band game a year. Anyway, DLC will no longer be sold by the end of February.
Maybe Activision is learning, or since they still have faith in the Tony Hawk franchise after Shred failed so hard they need more hard lessons. Will Call of Duty be next? Only time will tell. Anyway my next review should be up later tonight.
