The Kojima Challenge: Can you tell the new Fox Engine from reality?

We've heard exciting news recently on the Unreal Engine and Frostbite fronts, but what of Kojima Productions' internally-developed Fox Engine? The studio released some renders from its newly-updated graphics platform this week (via Andriasang); characteristic of anything associated with Hideo Kojima, you can have the pics and a free brain-puzzle for your troubles. Can you tell which of these images are real-life snapshots of Kojima Productions' conference-room, and which... are an illusion??

Trick question – all four of these images are Fox Engine renders. You didn't think Hideo Kojima would really have a horse in his conference-room, did you? That's the sort of thing a crazy person would do. The next Metal Gear title will use the upgraded Fox Engine – and, one can infer, will make all the game's incongruously-placed horses look pretty amazing.
