Isaac Haxton has appeared in a number of major final tables over his short career. He finished second in the 2007 PCA for $861k, and sixth in the 2008 EPT London High Rollers Event for $188k. Haxton also has a couple of WSOP final tables under his belt. Greg Raymer, as you well know, won the 2004 World Series of Poker. Raymer is an extremely capable poker player, and I wouldn't be surprised to see him win this event.
Vitaly Lunkin won a bracelet last year ($1,500 NLHE event for $629k), and will certainly be no pushover at the final table. Dani Stern and Lex Veldhuis don't have a great deal of "live" tournament experience, but both are extremely talented players who made their names playing online poker. Alec Torelli has a couple of major final table experiences to draw from, including a second place finish in the $10k Heads-Up event last year at the World Series of Poker.
Noah Schwartz appeared at the final table of the 2008 Borgata Winter Open, where he eventually finished in 4th place for $331k. Schwartz has nearly $800k in total lifetime tournament cashes. The remaining nine players will all be battling it out for the $1.89 million dollar first place prize, as well as the coveted WSOP bracelet.
