6) If tony was wacked (who really knows...) it would have been the "3rd" time someone/people actually tried to kill him, e.g., season 1 by the two black guys, season 5 by Junior, and at the diner (if that is what happened...again, who knows?).
Maybe the symbolyism is 3rd strike and your out? 3rd attempt on Tony's life (if that is what the cut to black symbolized) is his 3rd strike. Who knows. I just don't believe in conincidences, especially in a show where every detail is carefully scripted and thought out.
No that's not right. There are at least 2 more attempts to kill Tony.
The rat in College who did want to kill Tony in front of the motel, but it failed...
Patsy Parisi in Season 3 wanted to kill Tony in front of his house but in the end he only peed into the pool.
So there were at least 5 attempts to murder Tony.
