Mersaydeez, a poster at Survivor Sucks has basically called pretty much the entire season.
Her predictions have been right all along the way, e.g. Ulong would be decimated, only one Ulongan, who she rightly predicted as Stephenie, would make the jury, Gregg would win a reward challenge and take Jenn and more.
She predicts the final two will be Tom and Katie.
According to Wezzie a long standing and respected "spoiler",
Tom wins the first IC and Jenn is booted.
The final IC is endurance (as is generally the case). Katie drops out first and three hours later Ian gives up and asks Tom that he take Katie to the final two. Probst goes ballistic apparently.
Make of this what you will, but as I say Mersaydeez has been accurate since before the series even started and Wezzie has a great record of spoiling accurately through many seasons of the show.
