I think you must have followed the Aronian-Anand game from Wijk aan Zee January 2013 ty. If you have not, you have missed a treat! I followed the game from more than one source and the point I want to emphasize is the vital understanding of the Openings Theory which is crucial. Particularly as Aronian himself is a world-class player! Carlsen is expected to win the CT 2013 and Anand is no write-off, though I expect Carlsen to win but not very easily!
The columns about Corr. Chess on ChessCafe website are also very interesting!
