VGChartz revealed that Konami’s Metal Gear Solid 4 sold an estimated 1.3 million copies in it’s first day, pushing over 350K units to Japan and 400K units to North America.
“The American release of Metal Gear Solid 4, combined with the $100 Playstation 3 giftcard offer at retailer Walmart resulted in a 180% increase of Playstation 3 hardware sales. The 70,000 Metal Gear Solid 4 bundles supplied by Sony sold out immediately and with no confirmation of further shipments, it is expected that the hardware boost will be short-lived and PS3 sales will return to normal levels within the next couple of weeks.”
