Black Ops sold over 23 million units and over 18 million map packs in first nine months

Activision had another conference call today and released some staggering numbers.
Activision’s numbers show the latest CoD entry as having moved over 18 million map packs since launch (which, priced at $15 a pop, works out to 270 million dollars in gross earnings), 7 million more than MW2 and 9 million more than WaW. Though the company isn’t projecting any map sales yet for the next installment in the CoD franchise,

Activision Publishing CEO Eric Hirshberg stated, “There’s plenty of runway this year, with 20 percent-plus expected growth in the HD console install base alone,” referring to the company’s expected sales of Modern Warfare 3 this holiday and beyond.
