FIDE has just released the various participants and their hosts for the coming FIDE Grand Prix cycle.
Notable absentees are :
Viswanathan Anand (IND)
Vladimir Kramnik (RUS)
Veselin Topalov (BUL)
Alexander Morozevich (RUS)
Interestingly enough, the participant for the host of Bulgaria is not Topalov but his second, Cheparinov, thereby most likely confirming that Topalov is indeed not taking part.
That makes the top 4 players not taking part. And when you organise a string of Grand Prix events without the top 4 players of the world participating, the events could fast turn into watersheds, dooming the events before they started. As always, FIDE chooses to make a mess of things.
So it looks like what Morozevich inferred in his interview about the top players not playing in the event was right.
