Sony, after declaring that its PlayStation 4 was out-selling the Xbox One almost two-to-one in January, has confirmed that it has sold a total of 5.3 million PS4s between its launch on November 15 and February 8. The Xbox One, by comparison, had sold 3 million units by the end of 2013. This is before the PS4 launches in its home country of Japan, too; once that occurs on February 22 we can expect the PS4 to surge even further ahead of the Xbox One.
