The next Candidates are supposed to be held in March 2016, but there's nothing said about the regulations of the cycle on the FIDE site, apart from that the World Cup 2015 is supposed to give the top two spots in the Candidates. For the 2014 Candidates I think the rating spots were picked from lists between August 2012 and July 2013. The Grand Prix series were suppose to start in May, but that event has been cancelled without ever getting a host, without any message from FIDE, so maybe the whole GP series is at risk.

Prediction for 2016 Candidates:

Caruana
Grischuk

He's currently second in the Grand Prix standings, and 4th on ratings (Anand/Carlsen/Caruana) will qualify in other ways, and Topalov, Grischuk and Aronian might qualify via World Cup, as might Nakamura.

Anand is already qualified for the 2016 candidates tournament, ref 2.1 in regulations:

Yes, I wrote this prior to the outcome of the World Championship match, thus Anand/Carlsen. Caruana is almost assured of qualification via ratings.

The selcetion process candidates is as follows: based on that the players selected. 1. Runners up of last WC match
2. Two candidates from Grand Prix series. 3 to be held out which 2 has been held at Baku and Tashkent.
3. 5 as per FIDE ranking
4. One candidate as per FIDE choice it can be anybody usually its a Russian. Last candidates it was Peter Svidler.
Now make your list.

That's not correct. See here:
http://en.wikipedia.org/wiki/World_Chess_Championship_2016
- The runner-up of the 2014 World Championship match (Anand)
- Two qualifiers from the FIDE Grand Prix 2014–15
- Two qualifiers from the Chess World Cup 2015
- Two qualifiers by rating
- An Organizer's Nominee
Also the Grand Prix has 4 stages. Each player only plays in 3 events, sitting out 1 event.

Will Wesley So or Hikaru Nakamura make it?
Nakamura is currently in 2nd in the Grand Prix standings, so he has a good chance to qualify through the Grand Prix or by rating. Wesley So is not participating in the Grand Prix, and the World Cup is a crap shoot, so he would most likely have to quailfy by rating, which will be less likely.

Based on the GRENKE tournament it appears Anand is in bad shape, but as the candidates is a year away his form at present is practically meaningless. People wrote him off after his 2013 loss to Carlsen and he came right back and qualified again. This time there is a year long gap, so who knows how he will perform. It's all down to that one event next March.
has there been any spots sealed? do they decide the top two highest rated players a year in advance? how about the london classic?
