While his bandmates are busy forming bands with Scott Ian of Anthrax and returning to hardcore, Fall Out Boy Pete Wentz has posted a blog entry addressing the uncertainty about the future of the band:

I don't know the future of Fall Out Boy. It's embarrassing to say one thing and then have the future dictate another. As far as I know Fall Out Boy is on break. As much as i dont have a solo project, I also can't predict that I'd ever play in Fall Out Boy again. Not due to personal relationships as much as a band we grew apart. In this statement I'd like to include there is the possibility that Fall Out Boy will play again without me or I will be a part of it when everyone is on the same page. It is no one's fault and there is no animosity about the decision. I felt as fans you deserve to know. There is no singular reason for this. The side projects or bands are supported by all members of the band. I am the single biggest fan of Fall Out Boy and if this is our legacy than so be it. I am proud of it.

Drummer Andy Hurley (of the aforementioned hardcore project) added:

It's not looking great right now, but when we went into the break it was for sure that we'd come back in 2 or 3 years. I still think we will come back, but I just don't know. There's no official decision one way or another. The whole point of the break was to just get away, and not think about it, and in 2 years or so, come back and decide where to go from there. The reason ive given of touring and recording straight for 7-8 years is absolutely true as well. It was just burning us all out. And everyone else. We did too much so fast. Going away and coming back fresh could only be a good thing.

The band released Folie á Deux in 2008.
