A Next Metal Gear is… very confusing

Well we know Kojima likes to tease but this one is just ridiculous. Konami have created a webpage with a cryptic code about what the new Metal Gear is going to be. It features an equation of an upside down exclamation point plus an exclamation point which equals a power button with an exclamation point. The last symbol is also similar to a power button you’ll find on an Xbox 360, DSi, Wii or basically anything with an on switch. But its green- which could be a valuable hint. More inside

Is it coming to the 360? Does the i refer to the DSi or multiple is in Wii? Another Metal Gear Ac!d title is not out of the question either. The URL of the site has MGST in it, so what does the T stand for? So many questions but no answers yet. What do you think it could be?
