Serena's 07 title I agree she got lucky if Petrova would be less of a headcase about how to close out a match properly (she also f*cked up vs Oudin this year). Now that I think of it, if it wasn't Azarenka's illness and Kuznetsova's headcase(like Petrova), Serena would of never have won this year's AO as well. 2 of her 3 AO were won based on luck lol.
Unless Clijsters plays the YEC (which I doubt will happen), Serena and Clijsters will probably never square off until AO (if it would happen).
As far as Henin goes, she'll definately have tennis rust by AO so that's why I don't believe she will win it (she'll probably lose to a pusher like Wozniacki for instance).
I dunno about Oudin, you seem to have high hopes because she has a great game (great FH, not a headcase) but she'll never win any cheap points off her serve and she seems like a terrible match up vs any pushers. Like the Radwanskas, the Wozniackis, the Jankovic (although she'll probably go down like crazy) will beat her on a constant basis I'm afraid but I might be wrong.
