So far we've heard rumors of an Xbox 360 version of Metal Gear Solid 4 or an Xbox Live Arcade version of the PS1's Metal Gear Solid due to the neon green lettering (via ), a Metal Gear Acid game due to the use of an exclamation point (via ), and a touch-enabled iPhone/iPod Metal Gear game due to the "i" and the URL containing the text "mgst" (via ). Since nearly every conceivable idea has been thrown out there already, we're going to claim the last spot left in the Next Metal Gear pool and guess it's a kart racer. Hey, that could be a speedometer at the end!
