"Simon prepares for a new season of Idol -- or should I say, his last season of Idol. Okay, I will. Because it is," Cowell's older brother Tony said during this week's The Cowell Factor with Tony Cowell segment on the Fames Games independent music radio show.
"As I sit here in the sunny Caribbean with my family, a press statement is being prepared, which will confirm what everyone expected: Simon will leave Idol at the end of 2010 to concentrate on bringing the American version of The X Factor to U.S. TV in 2011."
The contract -- which has also kept Cowell from appearing on-screen for America's Got Talent or any of his other American projects -- also included an agreement that prevented him from selling the rights to an American adaptation of The X Factor during the contract period.
However, last week London's The Times newspaper reported Cowell is in the process of finalizing a deal for an American The X Factor edition that would air on Fox and feature Cowell -- who created The X Factor and has served as the original British edition's lead judge since it launched in 2004 -- as its lead judge and begin filming in Los Angeles in September 2011.
Cowell's The X Factor agreement with Fox is reportedly expected to be signed in early 2010.
