MrG
Company announcements thus far refer to Usher as the “Headline Judge” and in other announcements reference is made to “celebrity Judges” suggesting more than one judge will participate. Hence it follows that any further Judge appointments will be made before the comp start date. However I stand to be corrected if wrong!

Perhaps Jok or CE or any of the more knowledgeable on this thread can clarify this.
