Here's the real deal. If you take a minute to read the end credits, you'll see that the guy sitting at the counter is "Nicky Leotardo", Phil Leotardo's nephew. Why would he show up at Holsten's in Bloomfield NJ the day/day after his uncle is murdered by Tony's guys? The guy in the booth with the USA hat is a guy that was ripped off by Christopher for some dvd players a while ago. What's he doing there? Those two black guys that walked into the store, they're identified in the credits as the same two people that shot Tony in an episode 2-3 years ago. Why are they there? In the beginning of this season, Bobby said to Tony that you never see it coming when you get wacked, everything is just dark. It seems most likely that the moment Tony sees Meadow walking into Holsten's is when a shootout takes place and Tony likely is killed. Tony's father was killed the same way - in a big public shootout while his son was present. The family was unharmed (as in Godfather 3). The end.
