The 70 millionth sale came as of Nov. 4, which includes all PS3 models since the system launched in 2006.
While Sony is discussing numbers it was quick to mention that there are now 3,590 PS3 games available, which amounts to 595 million games sold worldwide.
PlayStation Network, the PS3's free online service, is now available in 59 countries worldwide, while the PlayStation Move controller, which adds motion control similar to the Nintendo Wii, has sold more than 15 million units as of Nov. 11.
A meaningful milestone
While Sony and Microsoft battle it out in the console race, they're fighting for second place. Nintendo announced in September that the Wii reached 97.2 million sales since its launch.
Eyes are now turning toward the next generation of gaming hardware, which begins this month as the Wii U launches worldwide.
Rumors peg the new systems for release sometime toward the end of 2013, or even falling back into 2014, so hopefully Sony still has some life to squeeze out of the PS3.
A new PS3 model, dubbed "super slim", launched just a few months ago, so it seems Sony still has a few tricks up its sleeve before passing the torch to the console's successor.
