A premature FIDE press release that appeared on Monday was not signed by Kirsan Ilyumzhinov and there are claims that the final decision wasn't made until Tuesday. It does seem that the final specific venue is a source of dispute. Ilyumzhinov insists upon Skolkovo a small Moscow Science Park whilst the major sponsor Andrey Filatov and the Russian Chess Federation say that it should be the Pushkin Museum of Fine Arts.
I updated my page, 2012 Anand - Gelfand Title Match, to document the new information on that match, and added a new page for the 2011 Hou Yifan - Koneru Title Match. FIDE's ongoing incompetence in its relations with the press reminds me of those old slapstick movies where one of the characters gets his foot stuck in a bucket and then stumbles around trying to get it off. The difference with FIDE is that it happens again and again and again.
