Sony Computer Entertainment's Shuhei Yoshida wants his company's new game-streaming service, PlayStation Now, to be the Netflix of gaming. When it launches later this summer, it won't be. In fact, it's launching in open beta. "We have to walk before we run," Yoshida told us in an interview this week at E3, the game industry's big annual show in Los Angeles. He sees the service as a long-term plan, part of Sony's ongoing initiative to bring PlayStation games to many devices. And that plan is just kicking off.
