I don't think the last toaster is going to be Adama,Rosalyn,Starbuck,or Boltar ,seems to me they are all to obvious.I agree that it will be a suspect yet to be brought into question.
The though has crossed my mind,speaking of being cruel, will they wait until they find Earth to reveal the last Cylon and have it be a person poised to destroy the planet. Could even be a dooms day movie where it ends with the Destruction of Earth.
