I have a couple suggestions for 2007 TE:
1. Players should be able to choose racquets and other appearal from like a pro shop. (appearal such as: head bands, wrist bands, racquets, shoes, jerseys, shorts, ect...)
2. People should be able to choose between one-handed or two-handed forhand and backhand.
3. And maybe there should be like a place where you need to work at to get all your skills up. If so you should be able to save them and use that same character for anything on the game.
