If Djokovic is ahead in their hardcourt rivalry, its only by the smallest of margins, regarding their slam hardcourt meetings anyway.
And Djokovic leads in the non-slam hardcourt meetings, although Nadal beat Djokovic at the 2010 World Tour Finals in straight sets and Nadal also beat Djokovic at the Olympics. So those are big events.
Nadal hasn't "conquered" Djokovic on hardcourts, but in terms of head2head Nadal is a lot closer to Djokovic on hardcourts than Djokovic is to Nadal on clay. Apart from 2 wins over Nadal in 2011 (Madrid and Rome), Djokovic has done nothing to Nadal on clay.
I just meant that since Djokovic has defeated Nadal in seven straight finals on all surfaces in 2011, Nadal has not shown that he can conquer Djokovic OFF clay. That remains to be seen.
