In an interview with Kerrang!, Billie Joe said that 2008 would "be a fair estimate of the release date of their new Untitled Eighth Studio Album." In October 2007, Billie Joe said more on this new album, saying he had been writing new songs on the piano, and had around 45 of them. He said he wanted the new music to dig into what he's feeling during that time - which is middle-aged.
