I don't see Tony in jail; I'll be surprised if all of his nuclear family lives though. He made the comment, "they don't go after the kids." Perhaps in the old days of the Omerta, but the Sopranos operates in a different world.
Tony has already lost most of his organization - Christopher; Sal (and who could replace him as consigliere), Bobby. He's got Paulie and a few others whose names I never even learned. I hope he makes Phil swim with the fishes though.
Still, it sucks that this wild ride is about to end.
Wasn't it interesting that the fed gave him the heads up about stuff happening?
