Let's start out with a huge spoiler-in fact, I was just getting the thread on them all readied-Tiffany Michelle and Maria Ho are a team in the race this year! It was very suspicious that Tiffany, who was the last woman standing (17th place) at the 2008 Main Event, would not compete in the 2009 event, as she said that she was "going out of the country to film something" and that the WSOP comes around every summer and poker won't be going away. Maria, meanwhile, was the Last Woman Standing at the 2007 ME, and they are very good friends. There has been a picture of them seen at LAX and they have the rolly-style bags like how Christie and Jodi did last season! The race has JUST started filming, as Tiffany's last tweet (Twitter) was on the 13th. Both of them are musicians/actresses, with Maria having made the Hollywood week for AI season 3, and Tiffany appearing in many bit roles, as well as on an episode of This Hour Has 22 Minutes (a Canadian version of The Daily Show, but airing once a week). Maria is also fluent in Mandarin, which may or may not help them.
The reason why Tiffany couldn't do the main event is because the final 9 players take a 4-month break, and then in November the "November 9" play the final table over the course of a few days-and she would not be able to participate if she got that far.
