In an interview with Edge , SCEE president and CEO Jim Ryan explained that while the service will arrive in North America in early 2014, it may be some time before Europe gets to experience the benefits of the cloud-streaming service."So the plan is to begin with North America next year and the plan is to provide a streaming service that will allow for PS3 content initially to be streamed to firstly PS4 then PS Vita and then PS3," he said.Ryan admitted this was largely why no mention of Gaikai was made during Sony's Gamescom presentation, as it seemed incongruous to discuss a feature that they couldn't pin down a launch window for."At a show which is now pretty global in its reach but primarily aimed at a European audience, we didn't really want to start talking about the virtues of this great cloud-based service without knowing exactly when it'll come to Europe," he admitted."We've got a roadmap, there's just a few bumps along the road that need to be ironed out."Sony acquired Gaikai last year for a reported cost of $380 million , before announcing at the PlayStation 4 reveal event in February that the service will provide a range of features including instant demos, remote play of PS4 games on Vita and, crucially, the prospect of backwards compatibility by allowing legacy PlayStation titles to be played on the new console.
