Fox is reportedly mulling a revival of The X Factor, which would see Simon Cowell jumping ship from the British version (again) to re-launch the show in the States, Britain's Mirror reports. Cowell left the British version of The X Factor in 2010 to launch the American version, but after that was canceled, he returned to the judges' panel of the original show this year. According to the Mirror, the revamped X Factor would premiere in 2015, with Cowell on the judging panel.
