I concur with others. It will probably go something similar to what it is now for the future, another 10-7 in their next 17 matches, ending something like 20-14, similar to Sampras and Agassi. Djokovic is just a bit more explosive all around and tougher mentally. Murray has a more versatile game but it doesnt really give him the edge overall it seems.
