Where's Phil?

AC/DC released the publicity shots for their new album, "Rock Or Bust," due out December 2nd.  The shots of course don't include Malcolm Young, but his nephew Stevie instead. The real question is, where is drummer Phil Rudd? Rudd missed duefilming the videos last week for "Play Ball" and "Rock or Bust" due to a "family emergency," so it could just be that they took the photos last week, but it seems weird that the band wouldn't wait for Phil to take their picture. Is there something odd going on, or just us fans reading into something that isn't there?
