Power Hold'em Strategy by Negreanu

Negreanus book will be released in May, 2006 according to Amazon. I'm just wondering if anyone of you guys know who his "superstar contributors" are. On the cover of the book it says "the greatest young players in the world reveal their secrets...".

I'm assuming there are going to be a lot of succesful, young players writing the chapters in the book. I'm guessing Gus Hansen, Erick Lindgren, David Williams and probably some others. Do you have some ideas?
