Sony’s next-gen PlayStation 4 console has supposedly been in development since August of 2010, according to the online CV of an ex-SCEA R&D director.

Spotted by VideoGamer, the LinkedIn profile of Attilla Vass claims he began working on the graphics library and security of the “Next Generation PlayStation” from August 2010 to April 2012.

Before you claim it’s referring to the PlayStation Vita, Vass lists his work on Sony’s handheld separately, suggesting that the “Next Generation PlayStation” listing is referring to the PS4.

“In 1998 I started as the first engineer in the Playstation US R&D,” Vass’ profile reads.  “I worked on graphics ( COLLADA, PSGL ) and a lot of network related technologies ( advertising, telemetry, PVRs ) for the Playstation2-x, PSP, Vita and Next Generation platforms. Platform security was occupying most of my time at the last years… ”

The PS4 has been rumored to be in development for a while now, though Sony has refused to officially acknowledge the development of a next-gen console. The company has continued to deny rumors and express their commitment to the PS3 and recently released PlayStation Vita, though SCE chief executive Andrew House recently told MCV that Sony won’t talk about a new console until they feel they’ve made a “significant leap” from the current generation of tech.

Meanwhile, rumors continue to swirl around the next-gen PlayStation. In March, it was rumored that the PS4 has been codenamed “Orbis” and that there are plans to release the new system in late 2013. Whether or not that’s true or not remains to be seen, but sources do seem confident that the PS4 will arrive before the next Xbox system.
