According to a report from Digital Spy on Friday, SCEE's UK managing director Fergal Gara said Gaikai's involvement has not been given a release date and all PS4 titles are intended to be playable on PS Vita.
"Exactly what is in the box on day one I'm not sure has accurately been pinned down, and we're certainly not able to map out accurately today what you can expect from PS4, much like PS3 is you'll get a great experience on day one but it'll continue to evolve.
"The intention is that the vast majority of PS4 games will be playable on PlayStation Vita. I'm not the best guy to ask how easy that is, but my understanding is that it's pretty damn easy.
"Maybe some games where it's a little awkward to execute on PlayStation Vita, but that'll more be because of additional controls, say for camera functionality on PS4 that might transfer across neatly.
"But my understanding is, if you're using the standard controls of the analogue sticks and buttons, etc, then that'll transfer across very neatly and very easily.
"And for me, from what I took out that whole message was, we used to say PlayStation Vita is a PS3 in your pocket, well now we can very confidently say it's a PS4 in your pocket. So that is a great, great, great boost for PlayStation Vita," Gara said.
Gara then went on to talk about how a network connection will matter for people depending on the strength of it.
"It's Wifi connectivity which is what you need. I'm sure there might be a little devil in the detail about how strong is the Wifi connection, and is there a point at which the experience becomes less powerful.
"It is a fact that in many homes the gaming console sits underneath the TV in the family living room. So many mom and dads aren't gaming, but the kids are.
"They maybe get an hour or so a day between homework and parents' time when they can get a crack at the TV and the console, then they get thrown off it. But that doesn't have to be the way anymore.
"So you might be thrown out the living room or mom and dad want to watch whatever, but you don't have to stop playing with a Vita and PS4, of course, and you can continue largely the same experience and quality experience in the bedroom, the kitchen or whatever. I think there are some powerful touches in there," Gara said.
