This, to my knowledge, is the first refereed paper to be published on Rosetta's observations of C-G (and it's free to access!):
The rotation state of 67P/Churyumov-Gerasimenko from approach observations with the OSIRIS cameras on Rosetta |

The fact that the south side sublimes away faster than the north because it is facing the sun at perihelion provides a possible reason for the asymmetric position of the neck, offset from the centre line between the two lobes. When the contact binary formed the neck would have been on the centre line but the missing material has left it off to one side, giving the duck a north facing 'chin'. This narrative implies that at perihelion mass loss will occur more from the lobes than the neck, contrasting with what we see now as the northern hemi-object is illuminated. Let's see if that happens.
