Though the NPD Group decided long ago to keep data from its monthly sales numbers secret from the general public, some specific sales information for October's heavy hitters were revealed in the company's monthly research email.
According to the report, the DICE-developed shooter Battlefield 3 sold "just under" two million units between its October 25 launch and October 29, the final day in the company's October data tracking. Batman: Arkham City, from developer Rocksteady, pushed "over 1.5 million" units after its launch on October 18.
Id Software's Rage reportedly sold 550,000 across its three platforms between October 4 and October 29. These numbers, of course, do not account for all avenues of video game purchasing--specifically, digital distribution is not factored in. Assumption is that both Rage and Battlefield, games from developers with a strong legacy in the PC space, had strong digital sales.
According to internal EA estimates, for example, Battlefield 3 had sold five million units within one week of its launch. In contrast, Activision has claimed its latest Call of Duty title, Modern Warfare 3, has an "estimated sell-through" of 6.5 million units in the US and UK.
“Between Uncharted 3, Call of Duty: Modern Warfare 3, Elder Scrolls: Skyrim, and Zelda: Skyward Sword, I expect November to be a huge month for new physical retail sales," NPD analyst Anita Frazier added.
