Speaking to Engadget at E3, Yoshida revealed that, unlike with the PS3, remote play functionality will be handled by the machine itself. "On PlayStation4 , it just happens. You just make a PS4 game, it supports Remote Play," he said.
"The single biggest issue, why there are not many PlayStation 3 games that support Remote Play, was that it was optional -- the system didn't do much. The game has to set aside some memory or CPU to be able to do that"
Although Sony are making for easy implementation of remote play, they do ask developer's to make sure they take the handheld device's control scheme and other factors into account.
"Please make sure that when you play your games on Vita, the control is good. That's the minimum thing we're asking them to do," he added
There's no specific release date for the PS4 as of yet, but we do know it's due to hit shelves later this year.
