What the heck is AC/DC's New Album Title Gonna Be?

Well after various reports the new AC/DC album is going to be called 'Black Ice', I have heard from others this may not be the case. Here is a comment by an Anonymous Individual

FYI: I think the new AC/DC release is officially gonna be titled "Dirty Rythm" (there is a song referencing Black Ice on the album though)

Can anyone confirm or deny this? Incidentally, AC/DC will embark on an 18-month world tour beginning this October in Wilkes Barre, Pa.

And Now here is the title track from their last release 8 years ago, 2000's 'Stiff Upper Lip'.
