Is the FedEx going to derail?

This seems to be the million dollar question among all the tennis fans world over.Federer has set himself very high standards so that even a semi final exit is considered a disaster which in any other tennis player's career would go down as a good showing.But I feel Federer still has it in him to win half a dozen more grand slam titles,but it would take him a lot more effort than it took him for his first twelve grand slam titles as he has to fight his way among the young brigade of rising tennis stars-Djokovic,Nadal,Tsonga,Tipsarevic and lots more.
