It was announced yesterday during Actvision's Q4 and year-end financials that the series was being canceled.
In response to the ill new, Harmonix has said it was said to hear about the cancellation, and that it's "discouraging news," for fans of the band game genre.
"We were sad to hear yesterday that Activision was discontinuing development on Guitar Hero," a Harmonix spokesperson told Industry Gamers. "Our thoughts are with those who are losing their jobs, and we wish them the best of luck. The discontinuation of Guitar Hero is discouraging news for fans of the band game genre. As retail sales of Guitar Hero and Rock Band titles have slowed with time, we've been focused on building a robust digital platform for music gaming and have recently crested 2,500 songs available for play within Rock Band 3 ... Looking to the future, for fans that want to switch, we'd happily welcome you over into the world of Rock Band.
"It's been a wild battle of the bands since 2007, but we respect and appreciate all of the hard work and innovation of our peers who have shared the music gaming space with us, and we look forward to rocking in the future."
Meanwhile, a source close to Develop has said as many as a quarter of the studio staff at Guitar Hero studio Vicarious Visions, have been laid off. Estimates put the figure at 50 cuts within the company.
