PS Vita Remote Play of PS4 Games Will Work Through Internet, Confirmed by Shuhei Yoshida
After E3 2013 many Vita owners, including myself, had one big question. Will the remote play of games between PS4 and PS Vita work? This will mean you can stream your games from your PS4 to Vita, at home (local wi-fi), or online.
If you want this feature, time to freak out! Sony Worldwide Studi President Shuhei Yoshida pretty much confirmed that it will be possible after answering a question on Twitter.
