While Activision has been sharing the player numbers for its battle royale title Call of Duty: Warzone all year long, the publisher hasn't disclosed how many copies of its most recent release, Call of Duty: Modern Warfare, have been sold. However, it seems as though we might have our answer, with the total coming about in a rather strange way.

During today's Nvidia live stream which contained the first looks at the company's new line of RTX 30 Series graphics cards, the current sales of Call of Duty: Modern Warfare were seemingly given. When announcing that this year's release of Call of Duty Black Ops: Cold War will feature ray tracing-enhance visuals, Nvidia CEO Jensen Huang said that the last entry in the series, which would be that of Modern Warfare, had surpassed 30 million units to date. If this indeed true, that's quite the feat given that the title hasn't been out for a full year.

The only potential discrepancy here is that Huang didn't say Modern Warfare by name and instead only said that "the last Call of Duty" was what sold 30 million copies. With that in mind, technically, Warzone is the most recent "entry" in the series making this statement a bit more nebulous. Still, the fact that Huang also made clear that these were copies of the game that were sold, and Warzone is a free-to-play game, it's still almost certain that Modern Warfare was the title that he was singling out here.

Call of Duty has been a strong franchise for the past decade, but it's arguable that off the back of both Modern Warfare and Warzone, the series has never been bigger. We'll have to wait until later this year to see if Black Ops: Cold War can somehow find a way to sell even more units when it hits PS4, PS5, Xbox One, Xbox Series X, and PC on November 13.
