This story has been updated with details from an investors conference call with Microsoft.

Microsoft sold a total of 2 million Xbox consoles during the first three months of 2014, 1.2 million of which were Xbox Ones, the company announced today.

These numbers come as part of the company's quarterly earnings report being issued today. It's important to note that these figures reflect the number of consoles "sold in." In other words, it's the number of consoles that have been shipped to retailers, not the number that have actually been sold and are now sitting in consumers' homes.

Microsoft recently announced it has shipped more than 5 million Xbox Ones since it launched last year. In January, it provided the only official indication of the number of consoles sold through to consumers when it announced 3 million systems had been sold by the end of 2013.

While the number wasn't specifically called out, some simple math tells us roughly 800,000 Xbox 360s were sold in to retailers from January through the end of March, a strong figure for a system that is now more than eight years old. Microsoft says sales of 360 "exceeded expectations."

Microsoft also reports that revenue for the entire Xbox platform--taking into account Xbox One, Xbox 360, and Xbox Live--was up 45% during the quarter, which ran from January 1, 2014 - March 31. Xbox One owners are using the platform for almost five hours per day, no doubt thanks in large part to services like Netflix and the ability to connect a cable box via HDMI to watch TV through the system.

The 2 million consoles shipped is, as you'd expect, well behind the number posted during the final quarter of calendar 2013 (7.4 million), but well above the 1.3 million sold during the first three months of 2013 (when Xbox One was not yet on the market).

Microsoft is holding a conference call with investors this afternoon, so expect to hear more on Xbox One's sales performance soon.
