PS3 is not supported for AIR. I believe the last verision of Flash Player that works with PS3 is Flash Player 9.
Current AIR system requirements: http://www.adobe.com/products/air/tech-specs.html
FWIW please let me register my desire for PS3 (and soon, PS4) support from AIR. When it comes time for me to port next year, I would prefer to stay in AIR rather than going through the painful process of either rewriting my game or trying to shoehorn it into ScaleForm as a wrapper.
