Metal Gear Solid 4 ships nearly four million worldwide

Metal Gear Solid 4 has shipped 3.94 million units worldwide, according to a recent sales report from Konami.
We don’t know the exact number of copies sold, but about one out of every four or five PS3 owners has purchased Metal Gear Solid 4. Simply put, there’s a lot of tactical espionage action going on.
With sales that have started to become slightly sluggish in Japan, will the game reach the lucrative five million sold mark before the end of the year? [PSU]
