Probably some of the same cast that played in the main-event at WPT-Biloxi I guess.
Probably not many of the biggest of the big names though as I assume many of those players will be at the WSOP-Europe which runs from Sept 6-16.
Some that were at WPT-Biloxi who might be hiking up the road to Tunica for the WSOP-C main-event there include:
Bill Gazes, Shannon Shorr, TJ Cloutier, Nam Le, Vanessa Rousso, Bernard Lee, Capt Tom Franklin, Mark Seif, JC Tran, Haralabos who were all mentioned on the update page on pokerpages.com

Even some of those players might opt to head up to the WPT-Borgata events instead.
