Let’s say Tony lives at the shows ending as one can imagine was the case if they ever did shoot the rumored movie. We know that Carlo was going to rat so I can imagine Tony and Paulie both go away during the trial if not permanently. Even if Silvio make it through all intact, Carlo has dirt on him, plus Silvio already did not like being top guy when he had the duty while Tony was in his coma so wouldn’t want it. Chris and Baccala are gone, that only leaves Benny and Walden left on the street in Tony’s crew. Unless Carlo can also provide evidence on Benny to convict him as well, who else could be the new boss?
