Well, in a bizarre turn of events, it seems like a 3rd party is farming it's franchise to a Nintendo house. As Silicion Knights, the creators of Eternal Darkness, will be handling Metal Gear Solid: Twin Snakes which is a remake of the original metal Gear Solid on the Ps2, well that's just weird, and still doesn't offer up the Twin Snakes thing, but the logo hints at something.
