In June, Develop speculated that Sony was so impressed with the Wii U controller's promise, they were mulling a similar feature with a link-up between their Playstation 3 console and upcoming handheld, the PS Vita. Their newfangled portable boasts enough power to run processor-hogs like Uncharted, so Wii U functionality appeared possible. Well, at Develop Conference 2011, Sony's head of R&D confirmed that you will be able to use Vita as a controller on the PS3.
"What could you do with all of this?" Phil Rogers posed to the audience at Develop, in regards to Vita's ability to communicate with a PS3. "Here's a few boring technical ideas: you could drive a display from a PS3 game, for example. PS3 can send data down to Vita and Vita can display it. You could use the unique features [of Vita] - gyroscope, touch front and back - as a control device for a PS3 game."
Rogers confirmed a linked-up Vita and PS3 can run software simultaneously, with no adverse affects to either console's processor power. However, Rogers stopped short of confirming all games could sport this feature, instead suggesting developers approach Sony with their ideas. I imagine Sony is waiting to gauge the reaction to Wii U's newfangled controller to properly judge how the market would react to such a potentially revolutionary feature. [Eurogamer]
