OK. David Chase, creator of the show, just called me and fed me the lowdown on tonight's season finale.
Don't read any further if you plan on watching the show...
1) In a surprise move, Tony divorces Carmella and makes the move on Artie Bucco. Artie is receptive and they are now live in lovers.
2) Carmella, feeling sexually inadequate as a result, goes on a wild spree and becomes pregnant by Furio, who flies in from Sicily to do the deed.
3) Meadow kills her fiance for the hell of it. She wants to me "made".
4) Johnny Sack gets butchered at the pork store. The former Mrs. Sack, all of her, feeling free after twenty years of a smothering marriage, becomes a nude dancer at the Bada Bing. Ten dollar bills are wedged amongst all the various nooks and crannies of her luscious form.
More details later, but I don't want to spoil all the surprises.
