Nice fantasy, Sammy--and one I share.
However, I'm aware of at least one snippet of film that's in the "Saga" version that didn't make it to the "extras" disc of the DVD set:
The scene with Michael meeting with Francesca and Gardiner Shaw (one of the best deleted scenes, IMO) ends, on the DVD "extras" disc, with Michael walking them out and saying, "Of course, you have my blessing." But in the Saga version, there's another four or five seconds after that in which Michael greets a hulking young man in a plaid sportscoat with, "How are you, Santino?" "Fine, Uncle Michael," he replies. Tiny as it is, the snippet is important because we now see Sonny's second(?) son as a grown-up. I bet there are other examples that people here know about.
