We've clearly witnessed a changing of the guards since Wimbledon, everything seemed to be at a standstill on the mens side prior to that. Rafa owned the French, Roger owned Wimbledon and even hard courts, and the WTA was the WTA.
Now we have Federer completely fallen from grace, Rafa the clear #1 to anyone paying attention, and a bunch of other up and coming and hungry young competitors in the fray. The WTA, well, it's still the WTA but there are some really exciting young stars like Caroline Wozniacki an Agnes Radwanska to look forward to, both future top 5's.
As a bettor, you may be frustrated with some of the upsets occurring lately, but as a tennis follower you have to think this is good and refreshing for the sport...
