Guitar Hero
In 2015, Activision announced the first new title to the series in 5 years, "Guitar Hero Live", released in October 2015. The title is considered a reboot of the series, with development being performed by FreeStyleGames, who had developed the "DJ Hero" games previously. As of December 1, 2018, Activision disabled the GHTV servers for Guitar Hero Live, reducing playable content from approximately 500 songs to 42 on disc tracks.

Another potential "Guitar Hero" project was discovered by the archival site Unseen64 for a game titled "Hero World", a massively multiplayer online game that would link the "Guitar Hero" and "DJ Hero" games. The game had been developed by FreeStyleGames, sometime after the release of "DJ Hero 2", with the main development duties passed to Virtual Fairground, using their platform The Ride, an Adobe Flash-based platform that would let the game be played in a web browser. The game was cancelled in 2011 along with other pending "Guitar Hero" projects.
