I've already read an article predicting that Serena would win all four slams next year.
Scary thought, but based on what we saw in the second half of 2012, I don't blame the media for going all in with Serena. It could definitely happen if she's as healthy and focused in 2013. But I've already said how much Serena sucks the fun out of watching tennis for me, so I try not to think about it too much.
Truthfully, I prefer seeing Serena win instead of Vika, so "The Injured One" getting shut out would be a small consolation.
As for Maria, I like where she is with her game in many ways. If she stays healthy, I think she's now entering the peak of her career. She can play some great tennis in these next few years if she keeps that fire and desire. Her attitude remains awesome and she seems very content and happy with her life. If she continues to improve her game, there's no reason why she can't win several more tournaments and get to slam finals. Serena keeps me from making predictions in 2013. Remember, Maria made those 3 slam finals in the past two years with Serena struggling to return from her injury. She took great advantage of that. Based on the way Maria played this year, I would confidently predict at least 2 slam finals appearances with one victory for her in 2013 if Serena was out of the picture. But with her around, I'll take a cautious wait and see approach and hope for the best.
