To clear up some misconceptions. The feature they've shown that people are calling "lock-on" works a little different to actual lock-on.

Once a monster is in the same field as you are, an icon is enabled, you press it and it whirls the CAMERA around to the monster, but it doesn't stay on the monster unless you press L, which centres the camera on the monster again. It simply replaces the need to use the d-pad to move the camera around. This doesn't make hitting the monster easier than previous games.
