According to "trusted sources" speaking to Eurogamer, game streaming on PlayStation 4 powered by Gaikai will launch in the third quarter of 2014, with a European launch slated for sometime in 2015. Developers have been briefed on Gaikai, the report claims, and some have been asked to participate in a beta for the cloud service said to begin in 2014.
Sony has been pretty vague about this topic, saying only that Gaikai will launch for PS4 sometime during 2014 in North America. The service will roll out first on PS4, before coming to PlayStation 3 and PlayStation Vita later. Sony has remained silent on just what users can expect from the service, saying only that it will allow players immediate access to a catalog of "critically acclaimed" titles.
Speaking with Eurogamer, Sony Computer Entertainment president Andrew House reaffirmed that Gaikai is on track to launch in North America in 2014. "That remains the plan and we're very much on track to reach that," he said.
Sony acquired Gaikai in summer 2012 for $380 million.
