Sony's PlayStation 4 continues its dominance in the next-gen video game console sales battle, officially reaching six million units sold as of March 2.

According to USA Today, the announcement came just weeks after the console was released in Japan. The PS4 was released in the U.S. and Europe in Nov. The console's Feb. 22 launch in Japan marked the last country or region to get the PS4.

The Xbox One, on the other hand, was released worldwide on Nov. 22 and has sold about 3.5 million units to date, the Independent reported.

"I am absolutely delighted that PS4 is off to such a great start in Japan," Andrew House, President and Group CEO of Sony Computer Entertainment Inc., said in a press release. "The responses we have received for the PS4 system's integrated social capabilities have been phenomenal, and I couldn't be more thrilled that gamers are utilizing these unique features to engage, share, play and connect with users around the world.  SCE will continue to expand the world of PlayStation by growing its library of breakthrough games and bringing more innovative features and services only possible on PS4."

Sony is seeing encouraging signs from its PS4-exclusive title "Killzone: Shadow Fall," which has sold 2.1 million units. The company is also gearing up to release "inFamous: Second Son" later this month, also a PS4-exclusive title. The best seller list is still mostly made up of titles available on both the PS4 and the PS3, like "Call of Duty: Ghosts," "Assassin's Creed IV" and "Fifa 14."

March is also going to be key for the Xbox One and Xbox 360, as "Titanfall," a first-person shooter from the same people who helped make "Call of Duty," releases March 11 in North America and March 13 in Europe. Microsoft has also designated those release dates for the Xbox One and will release the game for the 360 console weeks later.
