The one difference from GODFATHER II is that at the end of that movie, although Michael had lost everything dear to him, he was still the undisputed king of the American mafia. Tony has never wielded that type of power and being that these are the waning days of the mob, compared to it's heyday, when Michael was in power, he never will. Michael had lost his very soul at this point but his megalomaniacal needs were still fed through his success in the underworld. Tony could end up a much bigger loser, he could lose both "families". I think much is going to be left up to the imagination. We'll have a better feel for it in a couple of days. I can't wait!
