Sopranos star Michael Imperioli says series creator David Chase is "on the fence" about a possible seventh season of the mob drama. "I heard a month ago that we were doing a seventh season, and then I heard we're not doing a seventh season," the actor told reporters Tuesday while promoting his upcoming four-episode arc on Law & Order. The Sopranos' sixth season, which isn't scheduled to premiere until April 2006, was expected to be the last.
