The ultimate survivor in the Amazon is crowned as the reality series wraps up its sixth edition. The final four players are whittled down to two and the seven-person jury votes for the winner. "It's a toss-up when we get to the final two," says host Jeff Probst. "It's not a sure thing." The big change in the finale, says Probst, is that the concluding vote takes place immediately following the last immunity challenge. "There's no time to think about it," he says.
