The developer behind such games as Grand Theft Auto and Manhunt, Rockstar North has announced its work, during the Sony keynote via Sony’s Jack Tretton, on upcoming PlayStation 3 exclusive “Agent“.

Agent takes players on a paranoid journey into the world of counter-intelligence, espionage and political assassinations during the height of the Cold War at the end of the 1970s.

“We have always enjoyed making action games, and with Agent we are making what we believe will be the ultimate action game,” said Sam Houser, Founder of Rockstar Games.

“Agent is a game we have wanted to make for a long time. The team in Edinburgh is doing an amazing job combining intense action, atmosphere and story in a great period setting to create something that feels quite unique. We cannot wait for people to experience this game.”

In the current issue of GameInformer, in their Loose Talk section, it reveals that they think that RockStar North are working hard on the next Grand Theft Auto installment and they have set an release date for this holiday 2009.

“We’re not talking about new DLC or a collection of previously available DLC, we’re talking about a full retail game,” explains Game Informer. “We expect this title to follow the suit of previous GTAs and use a subtitle such as GTA: San Andreas, etc. Tokyo might be a possible setting for the game, but details are non-existent currently.”

While this intelligence is massive for many,  if you look back down the road we may remember that when Grand Theft Auto 3 was released RockStar Games did managed to get GTA: Vice City in as little as 12 months. Rockstar Games also loves holiday release dates an they have released about eighth games launched in the holiday gaming schedule. A October 2009 release would allow around six months longer than was required for Vice City.

“This is a game that will deliver a rich, fast-paced and intense ‘Grand Theft Auto’ experience that will be truly unique to Nintendo’s handheld platform,” said Sam Houser, Founder of Rockstar Games. “Rockstar Leeds, along with…the….team at Rockstar North, has built upon a decade of progressive design on Grand Theft Auto, and has created something fundamentally fresh and immersive.”
