federer has started to decline, though he'll stick around a few more years and will win atleast 2 more slams.
nadal's tendinitis has started to catch up to him, as his play style is very straining on his body, especially on hardcourts.
nadal will burn out in 3 years max and federer won't be anywhere near what he is atm in 3 years...
this leaves the domination of tennis up for grabs for a few players: djokovic, tsonga, soderling, berdych, del potro, murray, cilic etc.
players that have their best ahead of them and are still to reach their prime. most big hitters with big serves.
out of all these there are two that i think will dominate the tour for years to come: del potro and murray
these two have already showed how good they are already, and they still haven't reached their prime
murray still has a long way to come on clay, but delpo is very comfortable on that surface. likewise delpo has a way to come on grass, while murray is comfortable on it.
both have 3 slams they can win, maybe 4 if they can improve on the other surface.
as the us open is coming, i think murray is one of the heavy favourites for the title. since delpo isn't in his way because of injury, i think he'll grab his first slam title this year at the us open.
next year, both will be here, and both will hopefully be healthy and fit and playing their best tennis. both can play well at the aus open, so either of them can win. since nadal isn't as comfortable on hard as them, and federer isn't at his best anymore, i think delpo or murray will win the aus open. rg will be nadal's, wimbledon will be federer, then back to hardcourt slams.
this is the timeline of how i think the next few slam winners will be:
2010: UO: Murray
2011: AO: Murray
2011: RG: Nadal
2011 Wim: Federer
2011: UO: Del Potro
2012: AO: Murray
2012: RG: Nadal
2012: Wim: Federer
2012: UO: Murray
2013: AO: Del Potro
2013: RG: Del Potro
2013: Wim: Murray
2013: UO: Del Potro
this is how i think the next few years will go in the slams, murray and del potro dominating hardcourt, murray dominating grass and del potro dominating clay. nadal will win the next few roland garros titles, but del potro will start to take over. federer will win another two wimbledon's then murray will take over.
the hardcourt masters will go to either murray or del potro, i think mostly to murray.
the claycourt masters will go to del potro, as murray isn't very comfortable on clay
now soderling, berdych could win a slam somewhere there i think, most likely on grass imo. and they could win a ms every now and then, but for a few years i think the dominating forces of tennis will be these two: juan martin del potro and andy murray. of course a new player could come along and dominate just like federer did, but it looks unlikely atm.
uber negative and plain wishful thinking.......murray was ripped apart like a banana leaf just a couple weeks ago and del potro is still not back on the tour.......
nadal is the one who has won 8 slams already and knows how to do it.......we are in the nadal era and they will have to fight like no other day to snatch even 1 slam from him in the next 1 year.......deal with it.......
