Some facts and figures are in after Call of Duty: Modern Warfare 2’s first day on the market. UK is reporting a record-breaking 1.23 million in sales, grossing £47 million (roughly $78.3 million) and smashing Grand Theft Auto IV’s first-day sales record of 631,000 (3.6 million U.S. and UK).

Gamestop announced before the game’s release that COD MW2 was its number one pre-order game of all time. Amazon is reporting the same success, announcing that the game is its biggest selling pre-order of all time, dethroning previous title-holder, World of Warcraft: Wrath of the Lich King.

But that’s not what takes the cake. VGChartz’s preliminary figures put worldwide sales at over 7 million copies with a breakdown of around 55% of sales on Xbox 360, 33% on PS3 and the remaining 12% on PC. According to VGChartz “Based on the day one figures and the Tuesday release, week one figures should come in at close to ten million units which smashes the 5.92 million week one record set by Grand Theft Auto 4 last year and positions Modern Warfare 2 as the most successful game launch of all time.”

UPDATE: Activision announced that 4.7 million copies sold in the first 24 hours belonged to the UK and U.S.

This highly anticipated game was predicted to be a best-seller. Though it was not without controversy, initial reports seem to indicate that analysts were correct!

Call of Duty: Modern Warfare 2 is available for PS3, Xbox 360 and PC.
