We really need some sort of "Shocker!" category for posts like this. A British band called "The Answer" have revealed that their music will be included in the next edition of the Guitar Hero franchise, which will be out before the end of the year. Watch as we remain unsurprised and, to be honest, completely indifferent to the news. Guitar Hero has largely been made irrelevant by Rock Band and we only expect things to get better for the game with the inclusion of over 200 songs coming in the next year.
No doubt Guitar Hero IV will still sell well when it's released at the end of the year, but in the meantime Rock Band will have sold many more million downloadable songs (judging from how quickly it reached the 2.5 million download mark). Activision is keeping tight-lipped about the whole thing, with no official game announcement having come yet. No doubt we'll hear about it during GDC or E3 later this year.
