The eligible systems for 2009 are: Xbox 360, Xbox Live Arcade, PS3, PlayStation Network, Wii, DS, Multi-Platform (Console), Multi-Platform (Handheld), Biggest Disappointment and Game of the Year. You'll be quick to notice that there is no PSP category. Seeing as the only PSP game I bought this year was Chinatown Wars, and I'm only rating system-exclusive games, the PSP has been excluded.
