The fatal flaw in the theory that Tony Soprano got whacked -- based on the man in the "Members Only" jacket going into the men's room, like in The Godfather, to fetch a gun -- is that Tony not only saw The Godfather, but had every scene memorized. Sopranos fans know this. The crew used to sit around talking about this or that event in "one," or "two," meaning Godfather I or II.
By the way, the most delicious scene in the grand finale was when son A.J. and his girlfriend were watching news clips of Karl Rove rapping and "dancing," along with Dub-Yuh trying on an African head dress on one of his African tours while laughing their asses off at the absurdity of our rulers.
