Depends on how she (read: label) wants her era to go, if she plans seperate dates for UK, US and worldwide, it could work, but XFactor takes a lot of time and will limit her promo for months, so if they plan a worldwide release around the same time, it could work backwards for her, this appearence is just good for her, she doesn't need a permanenent spot as judge imo. she needs high profile promo (as in performances/magazines/articles) in UK/US to built her way back up!
