The official site is something of a disaster. The domain name Chessmexico.com produces a blank page, so I included a link to the start page in English. Many of the images are broken and the 'Players' page doesn't list the four players who qualified from the candidate matches in June. With a little more than one month to the start of the event, someone should look after this.
Later: The broken images were my fault. I was running with Flash disabled, as I usually do. When I enabled it, the 'images' were fine.
