In my prior post, it seems I had the Candidates qualification priority a bit backwards. According to the regulations posted on FIDE's website, this is the priority for Candidates qualification:
1: Anand/Carlsen loser.
2, 3: World Cup Finalists
4, 5: Top two from Grand Prix
6, 7: Top two on the ratings list (average of Aug/2012 through July/2013, must have played in Grand Prix or World Cup to be considered)
8: Organizer nomination. (Must be rated at least 2725 in the July/2013 ratings list.)
So, we're currently looking at the following situation:
1: Anand/Carlsen loser
2: One of (Tomashevsky, Kamsky, Vachier-Lagrave, Caruana, Kramnik, Korobov, Andreikin, Svidler)
3: One of (Tomashevsky, Kamsky, Vachier-Lagrave, Caruana, Kramnik, Korobov, Andreikin, Svidler)
4: Topalov
5: One of (Mamadyarov, Grischuk, Caruana)
6: Aronian
7: Kramnik (next three qualifiers are, I believe, Karjakin, Caruana, then Nakamura)
8: ? (see list below)
If someone qualifies at a higher-priority level, an alternate is used for the lower-priority spot. So, as an example, if Kramnik makes the finals of the World Cup, he qualifies that way, and Karjakin would get spot #7.
Got it?
And, FWIW, the pool of possible organizer nominations is below. Remember if any of these players qualify for spots 2, 3, 5, or 7 above, they get removed from this list. Players already in the candidates (or the world champ) aren't listed. Players are listed in ratings order from the July 2013 ratings list.
Caruana, Grischuk, Karjakin, Nakamura, Gelfand, Kamsky, Mamedyarov, Dominguez Perez, Ponomariov, Wang, Svidler, Adams, Leko, Morozevich, Giri, Vitugov, Ivanchuk, Radjabov, Andreikin.
