Xbox Live’s Major Nelson just posted on his blog that the third installment of the Gears of War franchise has had a massive opening week selling over 3 million copies. A big contributor to those sales were the over 22,000 midnight launch events held around the world.

According to the posting this takes the Gears of War series to over 1 billion dollars in cumulative sales and makes it the highest grossing game of 2011 so far.  In an earlier blog post he reported that over 1 million of these sales were pre-orders from around the world. 

Is there any other game out there this year that will de-throne Gears of War 3?
