It seems that Tiesto will lend his name and music to a DJ Hero spin-off, which is most likely to take the form of a separate disc akin to Guitar Hero: Aerosmith. He also claims the title will be released next summer, suggesting that the standalone title will arrive before this.
Tiesto himself said in the letter: “I am very excited about this. I think this is a great way to introduce people into Djing. Maybe they realise it's not as easy as they think. I am sure this brings new fans to the scene. Dance music is not far from hip-hop for example. Hopefully the music I have composed appeals to all kinds of fans.”
