Take a look at the new "official" band photo....
...then take a look at the photo taken of the band during the Sundance film festival.
They are both taken by the same photographer, and unless the band likes to wear the same clothes all the time...it looks suspiciously like this has been in the works for a while. There would have been no reason to take a posed "band" photo back then.
Maybe it's just the conspiracy theorist coming out in me though...
