Gigwise), MTV senior vice president of home entertainment Paul DeGooyer said, "There are a couple of things we've committed to, one of them with Metallica for example. They've reserved the right to give us their first single from their new album for the game."
No word on a release date, the name of the song, or if the price of the song to download will fall in line with Rock Band's current $1.99 price. The single would be a huge boon for the game as it competes against the established Guitar Hero franchise, and interesting to think that the first time we'll be hearing the new single will be when we're drumming along to it.
Of course, the real winners here are Harmonix, who get the hear the single before any of us (how else will they program the song parts?). Let's hope no one in the development studio accidentally leaks the song onto P2P servers - you know how much Metallica likes that.
