Simon and Cheryl are not leaving. Simon has already said he's got some new plan so he can do both.

As its been said, Cheryl isnt really high profile enough there(though fairly known through gossip media and those hot woman polls etc) so I think she'll lose out to an American star. Though she does have big plans to launch her solo career there so she could be a future judge if she succeeds.

Can't see Dermot hosting XF USA either. Too unknown and nothing special at hosting. His attempts at banter with the judges always falls flat. And God forbid Christine Bleakley gets the UK gig. ITVs biggest new overpayed flop.
