Chessbase has a comprehensive article on the upcoming Candidates tournament, to determine the challenger for the next World Championship match against Carlsen.
All the usual suspects are playing – Anand (most recent former champ), Aronian (#2 in the world), Kramnik and Topalov (all former champs). Joining them are Karjakin (world record for youngest GM title, at 12 years 7 months), Mamedyarov, Svidler, and Dmitry Andreikin (who qualified by coming in 2nd in the World Cup last year).
Some may find the lineup to be not quite fair, rating-wise. Andreikin is currently 40th in the world, while 5-7th in the world (Caruana, Grischuk, Nakamura) are nowhere to be found. But they had their chance, and didn’t qualify. Better luck next year.
The tournament is a double round-robin, to ensure equal pairing and color allocation. First round is March 13th, and will take place in Russia.
I found the time control interesting, and excessively complicated:
3.5 Time control.
The time control for each game shall be: 120 minutes for the first 40 moves, 60 minutes for the next 20 moves and then 15 minutes for the rest of the game plus an additional 30 seconds per move starting from move 61.
I’m sure the games and live commentary will be available online during the tournament.
