According to the newsletter, the two new Warped Tour track packs will be hitting the Rock Band store on June 23rd and June 30th "on Xbox Live Marketplace", which we are going to assume means they'll be hitting the PlayStation Network two days later, as per usual. Specific tracks aren't listed in the newsletter, but the band selection seems pretty solid. They've listed The Devil Wears Prada, Underoath, Bad Religion, Chiodos, A Day to Remember, Thrice, and more, meaning if your favorite band isn't listed, there's still a chance they'll show up. Firmly believing you can never have too much Bad Religion, this pleases me.
We're sure that Harmonix won't keep us hanging for long, so stay tuned for specifics on these two tour tie-in track packs. Thanks to Darrin for passing on the newsletter!
