Marek Okon worked as a concept artist on The Last of Us. He posted a piece of art on his Facebook account with the text "let me tease you something... Its coming."
To me, this looks like Ellie from The Last of Us. But this could be anything -- fan art, torture, Ellie's cousin, the new lead for the next Uncharted.
Okon continued to tease after the piece saw a response, with many hoping that it might be a tease for the next The Last of Us game:
Nice art. Not nice teasing.
