1) the seed (as per the tournament) and ranking (as per the world) displayed by the player's score name.
2) Challenge system for incorrect balls.
3) Percentage for linemen to call the ball correctly in. Each linesmen will have a different percentage of correctly calling the shot in. Hence, if they are wrong, we can challenge!!

4) The audience needs to look better, and their heads are not moving to the ball as the old version of TE 2004-2005 update showed.
5) The audience should have a feature where they "boo" you (like the French Open, etc.). The audience will "root" for you when you play the Davis Cup in your host country, etc.
6) The ranking for our game will go down if we do not play the game enough (like sign up for tournaments). Of course, this feature can be disabled for those who just do not have time to play a round every day.
7) May be some fan mail, or news updates.
8) Stats update during the match. Break points converted, Challengers remaining, number of aces, etc.
Once I see some additional changes, I will buy the game!! TE 2009, ALL THE WAY.
