A couple of significant bombs were dropped earlier today during Activision’s quarterly financial conference, where reports swirled that massive layoffs at multiple divisions were handed out and that some of the company’s bigger titles were being ended.

As popularity in the music video games genre has slowly diminished, the studio has decided to shut down two of their popular titles including DJ Hero and the juggernaut that once was Guitar Hero, which had a new installment planned for 2011. At the moment Rock Band is the top title in said genre, so it only made sense for Activision to pull the plug and move on. And if the decline in popularity continues, the same fate is likely not too far off for Rock Band as well.
