In a new interview with GameTrailers, Sony Computer Entertainment President, Jack Tretton said that first-party alone, there are fifteen PlayStation 3 exclusive games in development. That’s not including third-party games such as Square Enix’s Final Fantasy XIV and Rockstar’s Agent.

We’ve compiled a list of what PlayStation 3 games are known so far. Take a look at the games that have already been heard of.

• EyePet (Q4 2009)
• God of War III (March 2010)
• Gran Turismo 5 (2010)
• Heavy Rain (Fall 2009)
• The Last Guardian (2010)
• MAG (Fall 2009)
• ModNation Racers (2010)
• Ratchet & Clank Future: A Crack In Time (Fall 2009)
• Uncharted 2: Among Theives (Fall 2009)
• White Knight Chronicles (2010)

This rather impressive list of first-party PlayStation 3 titles right here is only ten titles. So that must mean that there’s five PlayStation 3 games in development that have yet to be revealed. That is, unless Jack also included PlayStation Network titles in his statement. Let’s hope that he wasn’t.
