It looks like Sony’s PlayStation 3 is finally picking up some steam. According to the company's own internal estimates, since the new slim model went on sale for $299 just three weeks ago, the console has gone on to reach 1 million unit sales worldwide.

Sadly they didn't offer a specific breakdown by region. For what it's worth, on a separate statement SCEA head boss Jack Tretton said U.S. sales have jumped 300% from last year, putting the figure close to an amazing 690,000. We'll have to wait for NPD's monthly report to confirm how close to reality his claims are, but for now the company seems to be positioning itself quite nicely for the upcoming holiday season.

In addition to touting sales numbers at the company's Tokyo Game Show keynote, CEO Kaz Hirai went on to showcase the PS3 Motion Controller onstage, indicating that it is scheduled to launch in Spring 2010. He also confirmed that 13 first and third-party titles with motion support would be coming at some point next year, including Biohazard 5 (known in the U.S. as Resident Evil 5) and LittleBigPlanet.
