PS Vita will do remote play on all PS3 Games
According to an article published by Eurogamer, PlayStation Vita will be able to do remote play on all games for the PS3, and will be enabled into an future firmware update.
All games for PS3 will be able to be played on PS Vita, however only in 480×272 resolution, and will be upscaled to fill the screen.
In future games, developers will be able to start introducing 480p Vita specific modes to try to match up with the Vita’s OLED 960×544.
Some months ago Shushei Yoshiba streamed Killzone 3 to a PS Vita from a Playstation 3 at the latest Tokyo Game Show, the video is below:
