Looks like Gears of War 2 is riding the Cole Train all the way to the Imulsion bank, baby. Epic's global product manager, Guy Welch, informs GameDaily that Gears 2 has sold over 4 million units in its first two months, which is double that of the original during the same time frame.
Welch adds that the original Gears has sold over 5 million copies to date. Unless Gears 2 suddenly drops into an emergence hole, it should outsell its papa in the near future.
