September NPD: Sony "continues to redefine entertainment"

Sony's pumped about its September PS3 sales in the US. So much so, in fact, that boss Jack Tretton has claimed the company is changing the shape of "entertainment" as a whole.

"We are in the midst of one of the most exciting times for PlayStation as we continue to redefine entertainment experiences for consumers, both at home and on the go," Tretton said, pointing to the price drop for the Playstation 3 and the release of the PSPgo.

"We've made unprecedented strides in digital and mobile entertainment with the availability of PSPgo."

He added: "The best part is that we've only just begun an onslaught of relentless, rich content hitting throughout the fiscal year, including Ratchet and Clank Future: A Crack in Time, God of War III, MAG, and ModNation Racers."

"Relentless" is a great word. Get all the rest of the NPD news here. Thanks, Kotaku.
