Will Nadal progress into Quarter Final?

Nadal has so far demonstrated that he can play well on hard court as well. He was quarter finalist last year in US Open 2006. Can he performed better this year? Will he be able to maintain his winning streak and reached the final or even win the championship? No doubt he has all the capabilities be a winner in US Open but Federer is still his arch rival on hard court surface. Well i should include Djokovic as the other arch rival for Nadal. If all went well for the No.2 and No.3 seed, they will meet in the semifinal. That will be a match not to be missed!
