Better platforming, semi-open world but not as open as Assassin's Creed or inFamous. A [gold] trophy for completing the game shooting less than...10 enemies (but not a full no shooting playthrough, some shooty stuff is good), i.e. almost every chapter can be completed via stealth.
BTW Drake's deception was the fact he's not related to Sir Francis Drake, which Marlow handily reveals for us.
Yes I would like a bit more fleshing out of Nathan Drake as a character. Actually for UC 4 I'd rather go back in time, that way we can have Marlow and Eddy back in the game and we can get to know Drake better as to how he came to be the man he was in Uncharted DF. I don't know when he met Chloe, but you could contrive Chloe into a pre-DF story. You could also end UC4 with Drake convincing Elena to do that doco shoot with him.
Uncharted Origins, if you will. Although that was part of deceptions of course, still we shouild catch up with Nate and Sully a few years after they first meet.
