The center lock on the mode dial seems to be inherited from the 60D.
The "Canon" brand is positioned below the LCD, just like on the 7D and 1D IV, but on the 5D II it's on the edge.
The body in the second picture is a 1D X by the way. (edit: nicely spotted, Joes Dad)
One novelty is separate switch photo/movie mode on right to viewfinder. I don't think there were any switches like that before in Canon DLSR 
The 7D has one.
