The new game, which ships July 12 for PS3 and Xbox 360 (no PS2 game for the first time), has added a new collision system, new defensive maneuvers, and new visuals like 3D grass and fog (for those night games).
They shot it in 3D, and there have been all sorts of enhanced graphics, so this fog surrounds me and is used to dispel nasty people to great dramatic effect.
