Black Ops II sells 1M at GameStop midnight launch

Call of Duty: Black Ops II is off to a hot start. GameStop president Tony Bartel said in an email to Bloomberg today that the speciality retailer sold more than 1 million copies of Treyarch's new shooter at its midnight launch alone.

Additionally, analyst Michael Olson estimates that Black Ops II shifted between 6.5 million and 7.2 million units in day-one sales, which is on par with Call of Duty: Modern Warfare 3's day-one haul of 6.5 million units in 2011.

The most successful Call of Duty launch to date is Modern Warfare 3, which generated $775 million in revenue during its first five days last year. Activision has not announced official sales data for Black Ops II yet.
