Station casinos freeroll tourney

Does anyone here know much about the Station Casinos freeroll tournament? It is being advertised as $100,000, the first 3 places getting $20,000, $10,000 and $5,000, and paying something to the first 300 places. Hold-em, Stud and Omaha 8/b are all played.

Questions:
Has anyone played in this before, or is it new?
If it is not new, how many players have they had in years past?
Does anyone know the payout structure beyone what is stated above?
How do they rotate among the games?

Any info shared is much appreciated.

Thanks,
