read the comments, apparently as part of the interview, IGN left out an important quote..
"We've got the Uncharted project, which we've talked about, we've got DLC for The Last of Us, and we've got the remastered version [of The Last of Us]. We've got other projects (notice the plural so more than one other project(S) in the works that are in the very early stages. We have at least four different pretty significant things going on right now."
Yeah I read the whole interview on GameInformer. Very, very odd that IGN would leave out whar most of us wanted to hear.
