Just been looking at the official site blog - looks like they are trying to get a few stars from the sports world to join the event with the Olympic swimmer Michael Phelps been linked.
It seems sports players are doing pretty well in there conversion to poker based on the recent UKGPT events with Tony Cascairino winning the Bolton event and Wayne Mardle final tabling at Luton - so don't assume theyare fish if end up on your table.
For some reason I have a premonition I will be on the same table as Hellmuth - don't know why but I keep thinking this - hopefully I last long enough that I am still in when he arrives at the table :) !!
Anyway I have included link to the WSOPE blog as decent read.
