I'm guessing you're referring to the new order on the top 10 list. You'll notice there's a new drop-down and that the current default sorting is 'Year-to-Date'. If you switch to 'Career' sorting he will find his way to the top of the list once again. He'll be #1 on both lists very shortly once WGT awards him his PvP winnings from September's tournament.
Don't worry folks, he ain't going anywhere. :-)
*edit* damn my verbosity
