New official art for the Doctor Who 50th Anniversary features all eleven Doctors!

The BBC have just released an all new artwork image for the Doctor Who 50th Anniversary that features all eleven incarnations of the Doctor.  Seeing all eleven Doctors stand side by side like this looks amazing but the one thing that stands out is that Matt Smith, the eleven Doctor, is looking "at the camera" while the other ten Doctors are looking straight ahead. Could this be a symbolic gesture of some sort? Perhaps implying that he knows something is about to happen and that everything will change (as it has been hinted at about the 50th Anniversary special)? What do you think it could mean?
