I haven't been covering the Tal Memorial (I know ... I know). Anyway, here is a snippet of an interview with Morozevich just before the event:

"Q: Turning to the Tal Memorial, how do you assess its strength?

A: I personally have no doubt that this is the strongest event in the FIDE calendar, in terms of the quality of the players. Of course, there are some foreign events, which can boast a slightly higher average rating than the Memorial. But in most of them you only get four, maximum six, elite players. But to get a category 21 with ten players, as we have here, the organisers need to work extremely hard. They have invited practically all the greatest players in the world. Eight players from the first ten! Plus ex-FIDE world champion Ruslan Ponomariov, and Vassily Ivanchuk, who at the moment has a slightly lower rating than usual. "
