In a roundtable interview at Tokyo Game Show today, Sony Worldwide Studios president Shuhei Yoshida said that Sony plans to launch Gaikai cloud services with a library of PS3 games in North America next year.
A selection of games will be available at launch, which will expand over time - Yoshida mentioned that users will want a good selection of titles to browse through from the beginning, like with Netflix, so the plan is to launch with a decent number of available games. They will be available to play through PS4, PS Vita and the recently-announced Vita TV.
Sony will launch this service in 2014 in North America. Asked about plans for European territories, Yoshida had no specific timeframe to share, but it is likely to be after the North American launch.
