WSJ : PS4 "may allow users to compete against others using different hardware"
The new PlayStation also will allow players to share achievements on social networks through smoother links to Facebook or Twitter, while also enabling aspects such as sharing footage of game play online through YouTube, people familiar with Sony's plans said. Sony's new console may also allow users to compete against others using different hardware, such as smartphones and other portable devices, those people said.
So companies have been developing ways to run such software on server systems and stream it over the Internet to customers, an approach sometimes called "cloud gaming." One of them is Gaikai Inc., which was purchased by Sony last July for $380 million. The deal was spearheaded by Sony Chief Executive Kazuo Hirai, a former protégé to Mr. Kutaragi, who no longer plays a day-to-day role at the company.
Since the acquisition, Sony has been investing heavily to prepare Gaikai's technology to enhance its new console, the people familiar with Sony's plans said. Sony has been preparing the technology to be used to allow users to play current PlayStation 3 games on the device, making a broader array of titles available at the outset, these people said. The new device is also expected to play new games stored on optical discs.
But streaming could have implications beyond well-dedicated game machines, potentially allowing Sony's smartphones and televisions to tap into graphics-heavy games they can't play now. Andrew House, head of Sony's videogame unit, said in July that the Gaikai acquisition was a "recognition on Sony's part that the cloud and cloud-streaming technologies are going to have a profound and possibly a very positive impact."
