In a blog post from their MySpace page, Sum 41 stated that they have finished their new album and it will be coming out this summer.

Hello everyone. we have finished our new album. we still don’t have a name for it yet though. it will be coming out this summer. we are now about to start auditions to find a touring guitarist. we have no idea how long this will take so i can’t really tell you when we will be back on tour. if all goes well we should be back playing shows in mid april. we will keep you all updated here as frequently as possible. thanks for all your support and i can’t wait for you to hear this album.
