Slipknot drummer Joey Jordison is reported by Launch Radio Networks as saying that Slipknot will be writing their new album in January 2008 with it likely to be released in the spring of that year. Joey told Launch:

“We'll probably start touring a month or so before the album comes out, kind of the same way we did the Jagermeister Tour before 'Vol. 3' came out,” he said. “So we'll do something like that as well and we're looking at right now doing some European festivals next year, but nothing's in stone yet. You know, there's still some things to be worked out, but the main thing is, you know, the fans should know that there will be another Slipknot record.”

He also revealed that compared to their last release ‘Vol. 3: (The Subliminal Verses)’ will be “heavy as f***,” adding that it will also be “just as weird and as experimental” as that album.
