So what are your ideas on the ending of Sopranos?

Mine are Phil gets killed, so do Meadow and Carmella (likely an accidental car bomb). Paulie kills Tony thinking he can take over the NJ and NY businesses and then Anthony kills Paulie.

Anthony is the last living soprano and he takes over the business and at the very end he's sitting in Dr. Melfies office, which is exactly how the first episode started.
