Nadal rolling through the draw

The Australian Open has been going on for the past week, and so far there haven't been any major upsets on the men's side. Nadal, Federer, Djokovic, and Murray are all alive and playing well. Nadal has marched through the draw without dropping a set so far, and as the French Open, Wimbledon, and US Open champ, I'm sure he's the favorite here as well. Andy Murray has also not dropped a set yet, and if he and Nadal both win their next matches, they'll clash in the semis. Federer and Djokovic lurk in the other half of the draw. I haven't been able to watch much of the action, mainly because it takes place in the middle of the night here. I did see a little of the Roddick-Wawrinka match and was disappointed Andy couldn't put up more of a fight. So now the quarterfinals are set. I'm not great at predicting results, but if I had to guess I'd say Federer will meet Djokovic in the semis, and Murray will take on Nadal.
