The single comes in three versions, one LE and two REs. The LE has a DVD with the PV and making of on it. The REs just have a different B-side on them as well as the usual differences with editions like different CD jackets.
I guess this will mean they will have either a fall or winter album. My bet will be on winter because then they can do a tour in early 2012. But I guess we'll just have to wait and see in the end how that all plays out.
