Sony's said the announcement of Nintendo's Wii U will likely inspire PlayStation Vita developers to replicate the same concept by linking Vita and PS3.
SCE Worldwide Studios boss Shuhei Yoshida told Develop at E3 that studios are already carrying out "experiments" using Vita as a touch screen controller for PS3.
"It is very interesting the ways that Nintendo went with Wii U, and I was surprised it wasn't exactly as it had been rumoured," he said.
"Already people are starting to ask about linking Vita and PS3 to do something similar, in terms of using two screens, and having controls on the screen.
"That's very interesting, and we will have to experiment," he added, before suggesting that work is already, to an extent, underway.
"Lots of the things that developers of Vita games are doing, as you may have seen, is experimenting with connectivities between Vita and PS3.
"The Wipeout  team came up with their cross play ideas, and the other Vita teams have come up with ways of playing with two systems. It's just a matter of time, as we provide the SDKs to developers so they can make use of both PS3 and Vita, and they might come up with something interesting."
