I see Kvitova making a good run, with Azarenka losing early. Sharapova will also make a good run. Na will get to the quarters, and so will Bartoli. Wozniacki will make a decent run, and prove the haters run.
Azarenka should provide a semifinal spot, but I think she will not make it to the final. If Serena or Maria fail in early rounds, then we could have Kerber or even Stosur in the final. I feel she is finally ready to show stellar tennis to home crowd. I also expect from Kvitova and Ivanovic to go far, quarterfinals or even semis for one of them, maybe both, who knows.
