Thronecoming was filed for trademark on July 26, 2014.
Aside from deluxe Briar Beauty, each Thronecoming doll comes with a diary.
It is unknown if the budget line will have diaries.
There is a TV special which aired in Late 2014 that features the Thronecoming looks. Fans will be asked to vote for one of the candidates for Thronecoming Queen, after which there'll be a follow-up short, presumably "And the Thronecoming Queen Is...", some time after the TV special that sees the winner crowned and on A Tale of Two Parties.
