This picture is from Sony's presentation at the Gamestop expo currently ongoing. Notice that all of the pics are of confirmed PS4 games except Uncharted 3. Does this mean Uncharted 3 is being remastered for PS4, or perhaps all of the old Uncharteds are??
Actually, Ratchet and Clank: Into the Nexus is also pictured. Maybe it's getting ported too.
