That's the whole point, I think. The show hurrying to get things wrapped up, mirrored Tony's attempts in the show, to get both of his families in order during and after the whole war...And then it just abruptly ended. Like a real bosses life should he have been whacked in the real world, he never got to see his plan play out, though he was expecting to, it never happened. He'll never get to see Meadow get married, or AJ succeed with the movie thing, or restore his marriage with Carmela, just like we won't get to see it. People seem to forget that the whole show was done through Tony's point of view. So when his light was snuffed out so abruptly, our view into his world went right along with it.
