long interview at the link,  this part caught my attention.  I thought we have seen all the DLC?

"We have multiple projects going. We never were able to fully staff two completely independent teams. At this point, I don't think we'll probably get there. 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 in the works that are in the very early stages. We have at least four different pretty significant things going on right now."

Uncharted PS4, LOU PS4, LOU DLC, and a 4th early stage game. Seems legit. They got their hands busy.

Uncharted collection for PS4 would be good.

its most likely the last of us 2

Crash Bandicoot PS4? Jak and Daxter 4? It's most likely The Last of Us 2!
