It was followed by the shooter "Fallout: New Vegas" from Bethesda Softworks and "Medal of Honor" from Electronic Arts Inc. The number doesn't include "Call of Duty: Black Ops," which went on sale Nov. 9 and shattered the entertainment industry sales record held by its predecessor, "Call of Duty: Modern Warfare 2."

Reggie Fils-Aime, the president of Nintendo of America, said in a recent interview he expects Nintendo to do well during the November-December holiday sales period.

"Last year, we sold close to 50 percent of hardware on (the holidays)," he said. While Nintendo is not planning to cut the price of the $199 , Fils-Aime added that some retailers are doing this on their own as they work to lure shoppers into their stores.
