Turns out, the hysterically hyped upcoming sixth season of The Sopranos may not be the HBO mob hit's last after all. Said series creator David Chase Tuesday at a forum sponsored by The New Yorker and Syracuse University: "I really enjoy [doing the show], so why leave something like that? It's just a question of whether the story works out creatively in six seasons, which I think it will." On the other hand, he added, a seventh season isn't out of the question, either. "It is possible." Hmm. Perhaps it's not a coincidence that Chase says Season 6 is going to revolve around "money and materialism."
