Whatever is going to happen it ends this week. So there are only a few possibility. Not enough time for the Tony goes to jail theory to play out. So, most think T buys it. I don't think so. David Chase has been criticized for glorifying Mob life. I think he's going to rectify that, but in a way worse than death.
The only one left is Paulie. And Pailie has been too comfy with NY. He's going to rat Tony out, but get it wrong as usual. He's going to lead Phil to Tony's family, where Carm, Meadow and AJ will be rubbed out. Seeing how Tony's cousin rubbed out Phil's brother which drove the whole NY-NJ war, its a fitting end. Tony will be completely isolated, alone and suicidal. Perhaps then he takes his life.
