Action vault has up a Q&A with Dallas Dickenson:
Action Vault: What range of statistics do you track, and how much of this information do you make available to the players?
Dallas Dickinson: We track a ton of stuff. What weapons people use, what Certifications they have, what weapons get the most kills, which bases (and continents) are most contested. Less of this is available to the players (though some clever folks have figured out ways to cull MyPlanetSide for data).
