I think the show has always been about Tony's real family at heart, with the mafia family on the side. I have no complaints about how much of each they show. Nice balance to me.
I've heard they're doing 12 episodes starting in March, then about 6 more in the Fall to end it...
Then I've also heard they're gonna do all of that, but have some kind of bombshell in the final episode that'll be concluded in some HBO movie.
Either way, can't wait for it, s'gonna be good.
