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 |

This preferential sublimation process seems interesting to me in for example how it might be modeled. Good food for thought with Gerald's scenarios. It also seems plausible in explaining some other similarly shaped comets.

What still keeps me from accepting the excavated neck story are the large pits on the main body that are closest to the crack in the neck. These have the appearance of some of the other vent pits on both bodies. If they are indeed expired vents, then they had to have formed earlier than the scree/talus that now spills into them from the head. They do not match the valley wall morphology further up the neck; they are positioned facing outward relative to the main body, and circular as if not influenced by earlier neck material. I just can't conceive a history of their formation relative to neck material deflation that would have been happening at the same time, were this a unified object rather than a piece rotated into place at a later era. I see the refill history of those pits as telling something about the sequence of activity/erosion in the neck.
