No insider information here, but from the outside, the 4th edition of the London Chess Classic seems to have been incredibly well organised.
One of the things I liked about it was the decision to have and odd number of players so that every single round one of the GMs was available for the live streaming TV broadcast, where they commented on the games being played, answered some questions by the audience, Twitter, etc.
You could get a first hand look into the mind of some of the top GMs in the world. Very impressive!
I remember the broadcast from round 8. At one point, Short says:
Short: Aronian loves the system with c6+d5+Bg4. All Armenians like this system. If you're Armenian, you play this just like if you're Georgian, you play the Caro-Kann, and if you'e English, you play the Grand Prix attack. Magnus, What do you play if you're Norwegian?
Carlsen: If you're Norwegian you play 5 moves and then start thinking because you don't know any more theory!
