I have nothing with wich to base this on and I'm sorry to those who want a Part IV (I used to be in this group) but I just don't think it will be done. When Mario Puzo (R.I.P.) died any hope of a Godfather IV died with him. Unless F.F.C. teams up with like Martin Scorcese and/or Bryan Singer and Christopher McQuarrie Godfather IV without Pacino would be a disaster.
