Simon Cowell appears in a three-and-a-half minute promo for the American version of X Factor, released by Fox Thursday.
"I can assure you one thing: you will never see a show like this in America," Cowell says. "A lot is going to surprise you."
Cowell discusses the auditions, which will happen in front of "3 or 4,000 people" in Miami, New York, Seattle, Los Angeles, Dallas and Chicago and the $5 million prize.
On Wednesday, THR.com first reported Facebook voting will be allowed for final rounds.
The show is due to kick off this fall.
