The accompanying image may be a simple composite of Sony's next handheld and the Nico Nico Douga iPhone app, but a job listing hints at Dwango's intentions to bring its video service to PlayStation Vita.
Sony announced other social aspects of Vita, including free support for services like Twitter, Facebook and Foursquare, during its Gamescom press conference. No mention of Nico Nico Douga, but Dwango opened a job listing looking for a "consumer game service engineer" to handle development of such a service on Sony's portable hardware.
Here's the Japanese-language job listing, which asks for people with PSP and PSP networking experience, and mentions PlayStation Vita and NGP ("Next Generation Portable," the original codename for Vita).
Perhaps we'll learn more about this during Sony's Tokyo Game Show keynote in mid-September, where the company will detail its Japanese Vita plans.
