He will never do that.
He only added these 2 tournaments, Hamburg and Gstaad, to his schedule because of the early Wimbledon loss and as a trial for his new racquet. With age he tends to have a smaller schedule with only the slams, mandatory masters 1000, Halle and Basel (and the last couple years Rotterdam as well). I can't see his schedule changing too much from this.
I wouldn't be so sure. I think he likes the idea of visiting new places.
The masters aren't mandatory for him anymore.
He's just playing tennis for himself now.
