Well... that's what I got it when I first read that: they were not breaking up.
But then I read the creed is over thread... I'm confused, really confused.
It makes no sense a street date when you can't stand your band mates. PLus, if there are new compositions, it means they worked on something, otherwise it would be only unreleased material.
From my point of view, they're releasing a box. It doesn't mean they're not getting together for an album in the near or long future.
No words about the DVD though...
