PlayStation 4 could employ a multiple-tier subscription service, offering different levels of access in a style similar to a cable television company, Sony Worldwide Studios president Shuhei Yoshida tells The Guardian.
"We could have gold, silver or platinum levels of membership, something like that," Yoshida says. "We can do subscription services when we have more content – especially now that we have the Gaikai technology available. With one subscription you have access to thousands of games – that's our dream."
Yoshida says the PS4 will have more digital content than its predecessors, at least: Every game will be available as a download, while some will still be sold at retail. This makes it easier to host smaller games such as Jonathan Blow's The Witness, and it supports a broader range of payment models, such as free-to-play or subscription-based games.
"We're shifting our platform more and more to the digital side," he says. "PS4 will be similar to PS Vita in that every game will be available as a digital download, and some will also be available as a disc."
Yoshida previously confirmed that current-gen PSN games won't run natively on PS4, though emulation or cloud service plans aren't out of the question.
