Sony Plans To Launch Gaikai PS3 Library in 2014 - IGN

"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."
