The Guitar Hero division at Activision has made some changes to its executive tier. Former CEO Dan Rosensweig left the company to hook up with Chegg.com, a site that allows users to rent textbooks. The site recently broke $160 million in investor funding.

Activision’s former COO David Haddad will be taking up the mantle on the struggling franchise. There had been some speculation as to whether or not Rosensweig was fired due to the franchises suffering sales. Activision denies those rumors, claiming that the move was completely voluntary for all parties.

Whatever the case, we can hopefully expect some changes from a genre of games that has been reluctant to innovate.
