I don't know how you postpone something that wasn't really scheduled, but if anyone can pull off the rare preemptive postponement, it's FIDE. The chances of this match taking place in 2009 dropped to nil when the Topalov-Kamsky candidates match was delayed for so long. Now they have "agreed to postpone the World Championship match between World Champion GM Anand and Challenger GM Topalov until the latest April 20th, 2010 and asked for bids for the match." Yes, bids would be good. More on the FIDE meeting at ChessBase and FIDE.
Of more interest: "In 2011, there will be a Candidate Matches/Tournament consisting of GM Kamsky, the loser of the Anand-Topalov match, two players from the Grand Prix series and one player from the World Cup, two highest rated players not already qualified and a player nominated by the organizer. The winner will play the World Champion in 2011." That's the out-of-thin-air kickback candidates event Ilyumzhinov dropped on us last year with no justification whatsoever. As I said at the time, he doesn't make this up unless there was already money in play. Ridiculous. Giving the same players chance after chance until one of them wins is corrupt hackery.
