Otherwise Fed himself has said that his body will dictate how long he will continue on the tour.
Djokovic, Berdych, Tsonga, and Nadal are declining too. Perhaps not as quickly as Federer but they are. Murray is peaking now but he'll start to decline in an year or two as well. I think things will continue to get worse for Federer for a couple of years and then they're gonna gradually get better. For instance, I think a 35 year-old Federer will have a better chance against a 29 year-old Djokovic/Murray than a 32 year-old Federer will against a 26 year-old Djokovic/Murray. This is assuming Federer continues on the tour till he's 35.
