Remote Play between PS4 and PS Vita
It was revealed during the official PS4 reveal that the console will support direct Remote Play integration with the PlayStation Vita, allowing gamers to play PlayStation 4 games using their handheld console. This will enable players to pause or quit a game on their TV and start that same game on their Vita without losing any data.
Speaking to IGN, Sony's Shuhei Yoshida stated:
"...the Remote Play side will work. So we’re saying virtually every PS4 game will be playable with PS Vita via Remote Play, so you connect your Vita to your PS4, especially at home, it’s a great experience.”
He was also pressed during the interview to answer whether this feature would be available immediately at the launch of the PS4.
“I will be heartbroken if it doesn’t [work] day one," he said. "So day one, my expectation… we have to have all [PS4] games work on PS Vita, unless it’s a camera-only game.”
He also revealed that Sony and Gaikai are working closely together to reduce the latency problems that might plague the idea of Remote Play.
At the Game Developers Conference in 2013 it was announced that the PS4 and Vita will have their screens mirrored. That means unlike the PS3/Vita, one screen won’t be dead – they’ll both be showing the game. Plus, rather than needing to enter into a separate mode, you can start Remote Play at any time on the PS4.
