The PS Vita will need software designed specifically for the handheld to be used as a second controller on the PlayStation 4. In response to fan questions via Twitter, Sony’s Shuhei Yoshida briefly explained the controller functionality of the PS Vita on the PS4.
Games need to be programmed specifically to utilize the PS Vita as a controller
When asked if this “Ultimate Companion” could be used as a second controller on the new console, Yoshida replied that “In a normal sense, no. Unless a game is specifically programmed to allow such use of PS Vita” can the handheld device be used in such a way.
This PS Vita compatibility is one area where Sony has left a lot of PlayStation fans in the dark since the console’s announcement earlier this year. We heard that we’d be able to stream PS4 games to the PS Vita, but details have been few and far between about this and other cross-platform functionality on the device.
Though according to Yoshida’s comments it looks like its going to be in the hands of developers as to whether or not the Vita can be used for primary or even secondary game functions. With so many games taking advantage of second screen touch devices in the coming years, Vita fans are beginning to ask whether or not the handheld will be used for such things. Hopefully, we’ll get some clarification ahead of the holiday launch. Sony has been vocal but cryptic about why they believe the Vita could see a boost in sales due to the arrival of the PS4.
