The new features' purpose is to give variation between players of different skills, and the tech demos EA have to show off are very impressive. One example shows a player of low skill turning on the ball and scuffing his shot into the ground, where a more skillful player is able to turn and volley the ball into the target.

It's all background stuff that will be hard to notice while playing the game, but should go a long way towards giving FIFA 11 a more realistic feel.
