Xbox One surpasses 5 million units sold-in worldwide

Microsoft says it has sold more than 5 million Xbox One consoles to retailers since launch, according to an update from Yusuf Mehdi, Xbox corporate vice president of marketing, strategy and business.

Citing NPD Data, Microsoft said it sold an estimated 311,000 Xbox One consoles in March. During the same month, Titanfall for Xbox One was the number one selling game in the United States, according to NPD estimates, though sales figures for Respawn Entertainment's first-person shooter were not provided.

Xbox One's latest sales milestone follows an announcement from chief competitor Sony, who says it has sold more than 7 million PlayStation 4 consoles since launching in November 2013. A key distinction between the two sales numbers is that PS4 sales are reported as sold-through, or purchased by consumers, while Xbox One sales are reported as sold-in, or sold to retailers.

Despite trailing PS4 by some 2 million units, Mehdi said global Xbox One sales are "outpacing Xbox 360 by more than 60 percent at the same point in time."

According to an tweet from Sony's PlayStation Twitter account, which also cites NPD estimates, the PS4 was the top-selling console during March in the U.S.
