I think Venus will be pretty disappointed if she doesn't take the title this week. I can't see Molik defeating her tomorrow, and the semi-final would either be against Wozniaki or Zakopalova.
The bottom half is much more interesting, with Razzano and "Aces" Pin in seemingly great form. It's a little hit and miss with Pennetta and Mirza at the minute, but still, while I think each one of them could cause Venus a few problems in the final, I still fully expect her to take the title on Saturday.
As for Serena, the "easy" part of her draw is well and truly over..
Tomorrow's match against Kuznetsova will be a good measure of her play, but it's definitely going to be tough. I see her getting through it though, and probably going on to face Ivanovic in the semis (as well as Golovin is playing, I really can't see her taking revenge on Ana). Depending on Ivanovic's form, and obviously Serena's, this match could go either way. I imagine it to be a three setter, but Ivanovic just falling to the occasion.
I think Serena will probably take the title if anyone but Henin makes it through the top of the draw. If Justine powers past Hantuchova and Jankovic though, I'm scared for Serena in the final.
Venus - Yes
Serena - Possibly / Maybe not /
