Sony acquired Gaikai in June of 2012 from former Shiny Entertainment head and Gaikai founder David Perry. It's long been known that Sony hopes to use Gaikai's technology to stream PlayStation, PS2 and PS3 games to the PlayStation 4 in lieu of hardware-based backwards compatibility, but now it seems that Sony wants Gaikai to spread PlayStation software to non-PlayStation (and potentially non-Sony) devices.
"Speaking of the ultimate goal, we would like to deliver PlayStation games to all devices," Yoshida stated in an interview with Dengeki Online (translated by DualShockers). "So we're considering various things like PC, TVs, Blu-ray players, smartphones, and tablets."
"We hope to continue to expand not only to Sony devices, but even to devices other than Sony's," Yoshida added.
Yoshida's ultimate goal is to create a web of devices capable of streaming PlayStation content, with Sony's latest console serving as a hub for this activity. "We previously spoke about PlayStation going from hardware to something closer to a service, regardless of the device - of course PlayStation will still be the center, but I think we would like to expand to different things," Yoshida said.
