Probably with the deaths of Michale Andolini in Sicily in about 1894, Tom Hagen, Victor Corleone and Frank Corleone in about 1974, and Connie Corleone and Vincent Corleone in about 2005.

It would be a very, very dark storyline. Instead of all the Corleone family enemies eating it in the climactic scenes of the movie, which has been the case in GF I, II and III, and probably IV, in V ... the Corleones would be the ones to eat it.
