It seems like they didn't start really making the album until a month or so ago, so I'd be surprised to see a release as soon as September. I could be wrong though.
meh at least thats what i hope. they look so glad and peacefull with the process and it jsut feel like it would drop ( at least teh single ) sooner then we expect. maby even a new (non album ) song liek they did with qwerty.
