Sony on controller requirements for PlayStation Now

It looks like you'll need a DualShock 3 controller to use PlayStation Now game streaming on most devices, excluding the Vita and PlayStation 4. The newly-unveiled service will stream previous-gen PS games onto the PS4, PS3, Vita, and Bravia TVs, and further down the line other "internet-connected devices" such as smartphones and tablets.

Whenever it does reach tablets and smartphones, users will need a DualShock 3 to play, according to SCEA VP of Marketing John Koller.

"It needs to go through the DualShock," Koller told CVG. "The DualShock remains the key ingredient. So that controller experience needs to go perfectly. We didn't want to utilise touch screen or anything like that because the games are best played with a DualShock."

That said, as the above vid shows you can control PS Now on Vita using the handheld. We've double-checked that with a Sony representative, who also confirmed you can use a DualShock 4 to use it on PS4, while a DualShock 3 is needed on PS3 and with Bravia TVs.

PS Now is due for a full rollout in the summer, and it's coming to PS3 and PS4 first - a PS3 closed beta begins in the US towards the end of this month. You can either rent games individually or purchase a PS Now subscription, and in case you're wondering, you won't be able to stick a PS3 disc in a PS4 and unlock a game that way.

"Sony is saying no to that right now," is the negatory from Koller.
