So here is what I found out. The guy at the bar is also credited as Nikki Leotardo. The same actor played him in the first part of season 6 during a brief sit down concerning the future of Vito. That wasn't that long ago. Apparently, he is the nephew of Phil. Phil's brother Nikki Senior was killed in 1976 in a car accident. Absolutely Genius!!!! David Chase is truly rewarding the true fans who pay attention to detail.
So the point would have been that life continues and we may never know the end of the Sopranos. But if you pay attention to the history, you will find that all the answers lie in the characters in the restaurant. The trucker was the brother of the guy who was robbed by Christopher in Season 2. Remember the DVD players? The trucker had to identify the body. The boy scouts were in the train store and the brothas at the end were the ones who tried to kill Tony and only clipped him in the ear (was that season 2 or 3?).
Absolutely incredible!!!! There were three people in the restaurant who had reason to kill Tony and then it just ends. This was Chase's way of proving that he will not escape his past. It will not go on forever despite that he would like it to "don't stop". Not the fans!!! Tony would like it to keep going but just as we have to say goodbye, so does he
