Apparently Carlsen is dominating the event so far, conceding only 3 draws through ten games and winning the rest. Right now he sits at 8.5/10 with a 3008 performance rating, a full 1.5 points above second place. Who is in second place? Veselin Topalov. I certainly didn't expect him to score so well.
They're finishing rounds 11-15 of the rapid games (G/15'+10") on July 8th, will play rounds 1-15 of the blitz championship (G/3'+2") on July 9th, and will finish rounds 16-30 of blitz on July 10th. Here's a link detailing the action to this point.
