I've actually never watched the show until tonight, but we just got HBO and I decided to take the opportunity to see the finale, as talked about as it has been.
As I was sitting there watching it and listening to Journey, while the daughter was having trouble parallel parking, my guess was that Tony, his wife, and his son were all fixing to get gunned down, with the daughter's parking trouble saving her and allowing her to go on about life with her boyfriend or whatever. They kind of set it up that way, you had the possibility of the guy wearing the Carhartt vest, the guy at the counter who kept looking over at Tony (the most likely), or even the black gangsta guys that came in.
I, like the rest of you, thought the satellite died right there at the end, and I was about to go crazy.
Interesting ending. Just like the Seinfeld finale, it ended in a way that was completely unexpected.
