I hope Gravity could tie-in with Marvel to promote both Thor: Ragnarok (movie) and Ragnarok Online. After all, they're both based on Norse Mythology. It would be great opportunity for Gravity to introduce the game to those who are too young to play when RO was released in 2003.
Hope there could also be an in-game event to celebrate the movie release.
Thor: Ragnarok is scheduled to be released on November 3, 2017.
