It doesn't comport with my own theory about the show, but Matt's prediction would make for a pretty neat (and plausible) twist ending.

Also, is this Robert Iler quote suggestive, or am I just overanalyzing?:

Did he think Tony was ultimately a good father? “Yeah,” Mr. Iler said, but he added, “I think sometimes he loved his son, but he hated him a lot more of the time.”

Was a good father? As in, past tense? As in, one or both of them dies in the finale?

Okay, it was probably just the way the writer asked the question. I'll calm down now.
