“Let’s get ready to rock!!!” Don’t you ever undermine this statement because in this Guitar Hero you’ll be rocking all night long – that’s only if you can keep you fingers from melting off.

According to Joystiq, Activision has confirmed to them that Guitar Hero: Van Halen is indeed in development and will release sometime during the second half of this year.

Activision could not confirm any songs, and only said the game will contain Van Halen’s “greatest hits,” as well as guest acts such as Queen, Weezer, Blink-182, The Offspring, Queens of the Stone Age, and more.

However, they were told by Activision’s Senior Vice President of Global Brand Management that, “… this is definitely Van Halen, not Van Hagar,” which is a plus since David Lee Roth is back with the band and they just finished a successful tour.

In addition, they revealed that there’s a very slim chance that the rockers might show up at E3 2009.

According to the people at Primotech, the June issue of Game Informer has an exclusive cover story but, this time it’s not Gears of War it’s Guitar Hero IV. Just like many other Game Informers this one come with details for the new game from Activision.

"Due to the recent falling-out between Gibson and Activision, Guitar Hero IV’s guitars will not be licensed and instead will be custom-designed by the developer. They will incorporate a currently unrevealed feature that will “directly impact the way you play Guitar Hero in the future.”

"Rock stars can step into the studio to create their own songs and share them with other players online courtesy of the newly minted Guitar Hero Tunes service, but these tracks will be devoid of vocals."

"Players will even be able to design their own musicians, album art, and instruments on-screen from scratch."

"While no song titles were yet confirmed, Van Halen, The Eagles, Sublime, and Linkin Park will all be making appearances on the tracklist. All songs in the game will be master tracks."
