The draws have been announced here: Gentlemen's and Ladies' (in proper British speak).
Because it's always bad to make predictions, here are some thoughts:
On the women's side, I think Ana Ivanovic is going to take it. With Justine Henin out of the picture, I think Ivanovic is going to settle into her number one ranking and start to dominate the field. Her victory at French Open will prove to be her coming out party. My prediction is that she'll beat Maria Sharapova in the final.
As for the men, here's my crazy idea: I think Rafeal Nadal is going to win the whole thing. And not only that, I think he's going to beat Novak Djokovic in the final. Yup, I don't think Federer is going to continue his winning streak on grass. I'm betting he loses to Djokovic in the semifinals, just like he did at the 2008 Australian Open. Nadal is playing amazing tennis right now--case in point, he simply wallopped Federer at the French Open. And although Federer has been unstoppable on grass, I just think that this is Nadal's year. Having said all that, I kind of hope Federer proves me wrong on this because I'd like to see him break Pete Sampras' Grand Slam record.
