The Structure of Sopranos

By this point in the season it's become pretty clear that each episode belongs to an individual. Last night was Artie. The week before, Vito. The week before that, Johnnie Sac. The week before that, Paulie. The week before that, Silvio. The week before that, Carmela.

Next week it will be AJ, or so it looks from the preview. Do they have enough episodes for this? Or maybe this is how the show ends, by going through all of the main characters, giving them a show a piece. Tony will be last, I suppose.
