Gelfand and Kamsky are through, while the other two matches ended tied at 2-2 and will proceed to tie-breaking matches today. I'm still sticking to my earlier prediction that Aronian and Kramnik will move on from this round.
Update: It seems that Aronian fell, but Kramnik advanced. The next matches will feature Gelfand v. Kamsky, Kramnik v. Grischuk. Aronian was the highest seed of the 8 players coming into the matches.
