This is what this guy meant:

If you play the previous Assassin's Creed games, the targeting system involves you highlighting and locking your enemy/target before you execute the kill. AC III obviously has a new targeting system (automated, as they say) where the game itself chooses your target without highlighting/locking him like in the previous games. It is good, I saw it in one of the combat screenshots.
