GenieKnows Games Narrowing the field

In a perfectly logical move, Konami has quietly released a demo of Metal Gear Solid 4 onto the Japanese PlayStation Network.  For reference, Metal Gear Solid 4 was released in June of 2008 marking a five month span between game release and demo release.  The demo takes place during the first stage of the Metal Gear Solid 4 campaign in the Middle East.  There was no mention as to whether or not there will be a North America demo release.
