Uncharted 3 to contain split screen co-op?

An astute youtuber has uploaded hand recorded gameplay footage for the upcoming Uncharted 3 that teases at a potential split-screen mode.

If you look at the bottom right of the screen you can see a gun and ammo counter for a second players hub. Will there be split screen co-op after all? This still has yet to be confirmed, but it would definitely be interesting to see if this turns out to be true.
