On women's side the most interesting matchup can actually be the quarterfinals between 1 Serena Williams and 5 Maria Sharapova. The winner of this will likely win the whole tournament. There's no question that overall Serena has been better but at 34, her age could fail her against a still young 28 year old Maria. And if Serena wins this one, is it still realistic to consider this yet another year for a calendar grand slam? On the men's side it could be yet another boring Australian Open from the best ever player of that tournament who may see 15 Grand Slam titles before it's all done. Could this be the year #2 Andy Murray upsets the top seeded Novak Djokovic? Could Murray put together a strong enough year to move to #1? I am hoping for Sharapova and Murray to start this year off as an unpredictable one. Williams and Djokovic are arguably the best players of their gender, ever. Others were great in their prime, too but there's something monstrous about the way Williams has owned Sharapova of late (4 of 4 last two years) and Djokovic has owned Federer (5 of 7 last year) and Murray (6 of 7 last year) of late. The safe thing to predict are Grand Slams for the two top seeded players, but how boring would that be?
