A future PlayStation 3 firmware update will enable Vita Remote Play on all games, Eurogamer has learnt.
However, this will be only at the PlayStation Portable 480x272 resolution, which will be upscaled to fill the screen.
For future games, developers will be able to include Vita specific 480p modes, Eurogamer understands.
Vita's OLED display is actually capable of displaying games at 960×544 pixel resolution.
Vita Remote Play is how Sony's new handheld interacts with the PS3.
In a Tokyo Game Show demonstration Sony's Shuhei Yoshida played a brief section of Killzone 3 streamed into the device from a PlayStation 3 unit, noting how a few of the Dual Shock buttons missing on the Vita are mapped to the touchscreen.
Vita can also be used in co-operative play with PS3 games. While a colleague played through a specially constructed LittleBigPlanet 2 level with a Dual Shock controller, Yoshida controlled an aeroplane via the Vita's touch screen, helping Sackboy reach his goal by altering the environment.
Sony declined to comment when contacted by Eurogamer.
