You had one BIG mistake in your post:
everything sounded like it would come from ND EXCEPT:
"We've heard some complaints over the course of Uncharted 3's lifetime and we wanted to make the most appropriate changes to the game."
NEVER EVER WOULD ND use the word "complaints"
In the eyes of ND, everything from the community are comments, suggestions, and compliments...but never would anyone ever complain about the game. NEVER
