I can think of as many arguments for Tony being alive as for him being dead. Someone on a previous page referred to Schroedinger’s Tony (maybe that’s why they introduced the cat).
Chase has been called, again and again, the master of misdirection. All through the series there have been omens that foreshadow… nothing (Tony takes Paulie on the boat and everyone, including Tony and Paulie it seems, expects Tony to return alone), characters introduced and given story arcs and episodes, only to disappear (Hunter returns, but no sign of Vinnie’s kid or the Russian).
The final scene was framed solely to create tension, the feeling that something had to happen: the diner setting, the Boy Scouts in the corner, the cameras following extras into and around the diner, close-ups of the family sitting around the table and talking about mundane topics, Meadow’s parallel parking problems and her dash across the street.
But the tension was all just manufactured. Looked at from any other angle than a scene in a mob drama, it was all just a mundane “made in America” tableau. At least two previous seasons ended like this, with the family in a restaurant bonding/talking/arguing/ over trivia.
Could Tony have died right at the end, with Steve Perry shouting “Don’t Stop…” at him?
Arguments in favor: foreshadowing (the orange, the cat, the opening scene shot to look like Tony was already in a coffin, the discussion with Bobby about whether you hear the final shot or if everything just goes black, the probable desire of those loyal to Phil for revenge).
Arguments against: At this point in the arc, we’re not really aware of anyone specifically gunning for Tony – though it has to be a possibility, it would be coming out of left field.
My conclusion: Tony is dead. and Tony is alive. and AJ is right: the world is going to hell, and and the only things that we can really get worked up over is whether or not Paris goes to jail and whether David Chase respects his viewers or not…
