Well the old man is going to play his EIGHT TMC/WTF final, has won more than anyone in the tournament (both in titles and in match wins) and really shut our mouths shut 'cuz I was one of the people who thought Murray was going to beat him in straight sets.
The second set was a masterclass on how to attack, Roger played S&V in his serve and Chip&Charge on Murray's serve, he broke the Scot from *40-0 in one of the games, didn't waste a single BP.
I think the old man has a good shot of still being a GS contender next year, let's see how it goes but man, I don't see any of the current top 10 players (sans for Pics who's his same age) playing at that level when they are 31.

You cannot teach this kind of shot, it's pure reflexes and hand. 
Oh and a final piece of data to consider: Murray’s percentage of points won on his second serve (37%), and the number of returns Federer missed on second serves (0; he was 34 for 34).
Roger is not exactly known for his return prowess and Murray was the one serving better all week long... 
Simply amazing post Warrior Princess Arkulari! Iron Man Federer never ceases to surprise when least expected. Many had him ready for the retirement home after a poor US Open, and losing a final in Basel and not seeming to be too stellar here this year. But as we keep saying here in the castle, one can't count him out until he hangs up his magic wand!
He has one more match to go now, can "Iron Man" Federer beat "Mr. Fantastic" Djokovic to win his 7th title at the Masters Cup, his 7th title of the year, and tie Johnny McEnroe for his 77th career title? That's a lot of 7's. Or will Mr. Fantastic win his second Masters Cup and seal his #1 year on a winning note? The last one they played here, Federer dominated 6-1, 6-4. I hope to see a bit more competitive match. But who knows what each will bring?
Respectfully,
