Sony's Scott Rohde believes the Vita's connectivity with the PlayStation 3 is a better solution to multi-screen gaming than either Nintendo's Wii U Game Pad or Microsoft's Smart Glass mobile initiative.
"Because we have the Vita, I think we can do a lot of special things," the Worldwide Studios vice president told GamesIndustry.
"And remember, that Wii U tablet doesn't have a processor in it, so it's got to be fueled by that box sitting under your TV.
"We can do some pretty special things that you'll start to see on the floor this year and you'll see more over the upcoming months about what you can do when you actually have a processor in the thing that's in your hand as well."
Rohde talked up the Vita's cross-platform compatibility with the PS3 as another major differentiator.
"When you start to see how you can cross over between the two platforms - look at two of the titles that are here at E3, PlayStation All-Stars and Sly 4, for example," he said.
"Both available on Vita and PS3, and there's some sort of interactivity across the board. Developers are interested in that kind of stuff."
The executive also stressed, again, that the Vita is still in its early lifetime, and that an upcoming swathe of new releases will give it a shot in the arm.
