I would have to say Theatrical Version for now, but if a Godfather Part IV came out that filled in the rise of the Corleone Family in the 30's AND provided a suitable ending to the Godfather Saga with the end of the Corleone Family, then I would have to change it to Chronological, without deleted scenes. Check out my Basic GF IV Outline I've started writing in the GF IV section of the site to start getting an idea of what I'm talking about.
