The two men who consistently played the best tennis are in the finals and it should be a good one. As I said before, I'll be rooting for Andy Murray to end the 75-year drought by British men and finally win a major.
Nadal(24), Djokovic(23) and Murray(23) are obviously entering their prime and should be the face of men's tennis for the next 5 years. At 29 years old, Federer unfortunately is most likely finished. He may win another major or 2, most likely Wimbledon, but as it happens to the best of the best, age and top quality competition have caught up to him. I can see him finding his old form and getting hot for a 2-week stretch and win a GS, or if injuries slow down the other players, he may also benefit. Otherwise, he'll keep getting to the Quarter/Semi finals, only to be knocked out by one of the afore-mentioned players. None of this changes the fact that he's the greatest player in history.
I'm somewhat disappointed by the lack of quality play on the women's side. It's good see a likable player like Clijsters still playing and at the top of her game, but she's going to hang it up soon. The Williams sisters are thankully on their last legs, but no one else has stepped up. Where's Ana Ivanovic? Sharapova is a shell of her former self. Henin has retired for good. Maybe Wozniacki will become the next dominant women's player, but she has to win a major first. Otherwise, we just have a number of Russian and other European women, none of them household names, battling it out amongst each other.
