How is it pointless? Djok just took 6 hours to beat Nadal on Nadal's worst surface/Djok's favorite surface (just one month after Nadal switched to a heavier racquet, and after Nadal said he would not be able to adjust in time for the AO). There is a strong possibility that Nadal will win 2-3 slams this year. If that happens, that is awfully close to the record, given that Nadal would be in his PRIME entering 2013.
OK, I could somewhat agree with the first part. But a strong (?!) possibility that Rafa's going to win 2-3 GS this year? I highly doubt it. IMO the only one he could win is Roland Garros. Even Fed at Wimby and Murray at the USO have better chances than Nadal.
Conclusion, Nadal will never reach Fed's record of 16 Slams. None of the current players will.
