New artwork depicting third Team ICO game released

Initially coming from Sony's website seeking applicants for Team ICO's new project, and getting spread across the interwebs by TeamICOGamers, we've been teased with a strange piece of CG artwork for what appears to be the next game from Team ICO. What is it? It seems to be a giant hole. With a big chain going down it. It seems we can expect another insanely clever concept from the group that brought us ICO and Shadow of the Colossus. Perhaps the worlds the games take place in will somehow make sense in relation to one another after this new title. Perhaps not. Forgive our giddiness over such an abstract, vague piece of artwork -- but we'll look forward to new information!
