Sony's defining game is Gran Turismo, and the main game hasn't been released yet.
The thing is, the PS brand was mainly defined by third parties (though the PS1 did have Crash / Spyro), so Sony doesn't have games that will be as popular as Gears or Halo. I think they're trying to correct this, though I'm not sure they'll be able to pull it off.
