Sony plans to make all available PlayStation 4 games accessible for purchase and download from the console's online store, Sony Worldwide Studios president Shuhei Yoshida told The Guardian. He explained that the PS4 is following the lead set by the PS Vita, which already offers much of its content as a download-only proposition.
Yoshida also hinted at some changes to Sony's current PlayStation Plus subscription program. "We could have gold, silver, or platinum levels of membership, something like that," he said. Reading what he had to say though, it sounds like this might not be in place until well after day one of the console launch. "With one subscription you have access to thousands of games," he said of supporting legacy titles on the non-backwards compatible console, adding, "that's our dream."
Sony will undoubtedly be revealing plenty more in the coming months. Check out The Guardian's Q&A for the full rundown of what Yoshida had to say.
