During a corporate strategy meeting this week (detailed in this document) Sony president and CEO Kazuo Hirai said that the PlayStation 4 is already profitable for Sony on a hardware unit basis.
"It's been a hugely successful launch, but the key to the long term success of the platform lies in how solidly we can continue to grow the installed base," Hirai said. "In terms of game titles for PS4, as of April 13, 47 titles had been launched with a total of 20.5 million units being sold via retailers and over the network on the PlayStation Store. From a profitability perspective, PS4 is also already contributing profit on a hardware unit basis, establishing a very different business framework from that of previous platform businesses."
Since its launch in November of last year, Sony's newest console has sold more than 7 million units worldwide to-date (as of April 6), according to NPD data.
