I do not think Meadow and Finn will get married.

Also, I think Tony's fight at the end was due to the way Phil reacted about Johnny Sack. He wanted to make sure his guys didnt act that way about him.. trying reinstate his leadership and authority (not that Paulie will get "it", he has been drawing further away the last few seasons).
I also personally think Paulie will get whacked before Vito does.
