Federer's increasingly running into a wall against the other top 3 at slams - Djok, Nadal at one or more of AO, RG, USO, and now Murray as well at AO and Olympics with Wimby 12 the only exception. He's also been susceptible or close to an upset against the likes of Berdych, Tsonga, JMDP. I hope he can reverse this pattern, but if it continues or the losses mount, then I could see him retiring. Otherwise Fed himself has said that his body will dictate how long he will continue on the tour.
