Game streaming via the cloud will start with PS3 games in 2014 for North America while Europe & PS4 games comes later. Sony Computer Entertainment Europe President Jim Ryan said this to Gamereactor about streaming games:

“It’s gonna be pretty much a phased approach, and it’s gonna be phased in terms of geography and in terms of how we’ll do it. We’ll launch in North America in 2014. We are working to bring that service to other parts of the world, and most notably Europe, but you know, Europe is… I love Europe… It’s a great place to live  and it’s so different… You know, Scandinavia is different to Italy, to France and everything is different to the UK, but that difference makes it great to live there, but it makes it rather difficult to do stuff like introducing a cloud gaming service, because it’s just very fragmented. So there’s a lot of details to work through, and we are in the the process of doing that, but we don’t have a timeline for introduction outside North America. We will start with the streaming of PS3 games to both PS3 and PS4, and that will quickly be followed by PlayStation Vita as a client device.”

 

Ryan also mentioned plans for PS4 games:

“That’s also on the roadmap, but we’ll start with PS3 and then quickly it’ll migrate to content from other platforms.”
