The final two starting flights for Event #5: The Colossus $565 No-Limit Hold'em, drew even more massive crowds to the Rio All-Suites Hotel & Casino Saturday, ensuring it will go down in history as the largest tournament in live poker history by a rather wide margin.

With a number of refunds still to be processed and the final tally yet to be finally tallied, the official numbers will not be released until 5 p.m. Sunday when Day 2 of the event is now scheduled to begin. However, WSOP Vice President of Corporate Communications and Editor-in-Chief of WSOP.com Seth Palansky told PokerNews the number will be over 20,000 and could be as many as 22,000.

A number of players crossed the six-figure mark today, including Steven Geralis and Brit Simon Deadman, but with literally thousands of players bagging stacks, it's too early to call anyone a front runner in The Colossus right now.
