Tennis has not been the same since Sampras-Agassi or Mac-Connors. I think it's important that new rivalries develop. Don't even mention Nadal-Federer as a rivalry, because newsflash to Federer fans: Federer needs to actually BEAT Nadal to have a rivalry. Don't bring up that fluke Nasdaq final either. Maybe Gasquet/Monfils will step up and be able to challenge Nadal.
