That"s an excellent question, and one I don"t believe anyone can answer.
This is the first season to have Regional qualifiers, as pointed out by Kinboshi (Daniel) in another thread, so until the first one has been completed it would be difficult for anyone to predict. Even then, it would depend on the number of players that turn up to play, up to a maximum of 80.
All I can say is that the starting stack for each player will be 3,000 and the blind levels will be 30 minutes in duration - the existing National structure can be found just off the home page.
