If we continue with the comparisons, Two things come to mind after the last game.
- Roger is at the peak of his domination,like the 'Pete- Rafter' phase of 97-98, where sampras just managed to hold his own against Rafter.
- Roger is learning from Pete the ways to prolong his career,His much improved Serve was the main enabler for Rogers title defense. I think on the basis of groundstrokes alone, Nole and Davy'D seemed better.(It wasn't the case earlier).
So if we continue the analogy, we may see Federer strugglingin the next few years against upcming players like djokovic, ala how Sampras struggled with Safin and hewitt. However Federer will continue to win Slams for the next few years though i think the dominating phase is over.
P.S - Mytake on the Roger Pete debate-
I think, overall Roger has the better game, primarily due to his ability and results on clay. Pete though has the better career as of now. Remember Pete won his first slam when he was about 20 and the last when he was 31. Thats a long time.
