When TVGuide.com spoke with Cat Deeley on Monday night, the So You Think You Can Dance host previewed the "exciting but sad" week ahead for the four finalists. "It's going to be a very close call," she says, noting how underdogs such as Courtney have proven resilient with each elimination (see the 1:50 mark). "They all have strengths and weaknesses," she says. "It's up to America now" to choose a winner.

While a new champ will walk away Thursday evening with money and more, Cat hopes to have sent "19 people away with an amazing life experience."
