Sony Worldwide Studios president Shuhei Yoshida notes that the iOS App Store and Google Play have "totally shifted our way of thinking," detailing the company's plans for mobile cross-promotion in a recent interview with GamesIndustry International.

"Lots of people don't seek out game-specific info -- they're busy," Yoshida explains. "But because they use social network services, App Stores... Let's push our info to them. That's why we are creating the hook, releasing the official PlayStation apps on Android and iOS at the launch of PS4."

Yoshida cites specific plans the company has in mind for the PlayStation 4 launch title Knack.

"We're releasing a puzzle game themed around Knack that you can play for free," Yoshida said. "It's fun, and by playing the game you earn some items that you can use on PS4. People might be motivated, because they've already unlocked some items, to take a look at what this Knack game on the PS4 is all about."
