Activision has posted a new video teasing a game announcement which will take place at 15:00 GMT/10:00 EDT tomorrow.
The video features guitars, drums, a stage, and a cheering crowd. Either this is a new Guitar Hero or this year's Call of Duty has really changed.
Reports emerged in March that the game would be revealed this month, Activision apparently revealed the new Guitar Hero to German media two weeks ago. That story followed a Kotaku story from February which claimed the game will be released on PS4 and Xbox One this year.
The last entry in the Guitar Hero franchise was 2010's Guitar Hero: Warriors of Rock from Neversoft. The studio was then merged into Infinity Ward in May 2014.
Harmonix announced Rock Band 4 last month and the game is coming to PS4 and Xbox One this year.
