Agent listed as "currently in development" on Rockstar resume 

Agent rumors never die, they just go to sleep for a while. That's the case today at any rate, as Agent rumors have awoken from their slumber once more thanks to a resume posted by a Rockstar research video editor.

According to Superannuation, a staffer at Rockstar New York mentions Agent alongside Grand Theft Auto 5 as currently in development on his resume.

While its possible the game is still in the works four years after it was announced, if it is coming, it won't be released in 2013 - this is GTA 5's year.

Two years ago Take-Two chairman Strauss Zelnick said during an earning call Agent was "still in development," but in truth Rockstar and its parent have been quite on the subject and refuse to answer direct questions on the matter. When either respond anymore, "we have nothing to announce" is usually the answer given.

Agent had a long history before its E3 2009 announcement: it began life as a prototype for PS2 and Xbox at Rockstar San Diego in 2003 before being put on hold. A few years later it was resurrected and touted as a PS3 exclusive - for a while at least. Now, it's unclear since Rockstar remains silent on the matter.

Should the game which takes place during the height of the Cold War in the 70s finally come back into the light, it's likely we'll see it release on next-gen systems - either exclusively, or conjointly with PS3.
