Disney released new details and the name for Epcot's new Frozen themed ride under construction inside the former Maelstrom attraction building. The new ride will be called Frozen Ever After, and like the previous attraction, it will be a slow moving boat ride. From what I’ve been led to understand, the new ride will re-use much of the old flume layout and Maelstrom boats from before. The artwork released seems to show the point in the old ride where the boat would stop in front of the three trolls who would cast a magic spell and make your boat move backwards.
In the Frozen Ever After version it looks like you'll be face to face with Elsa inside her ice castle, as she sings and casts frozen waves of magic in the air all around you. According to the Orlando Sentinel the ride will feature many of the film's classic songs, a finale with fireworks as you are bid farewell by Elsa, Anna, Olaf, Sven and Kristof, and you'll pass by Wandering Oaken's Trading Post in the queue. The ride will also feature a number of cutting edge new animatronics that will feature internal projection based face animations, much like those used on the Seven Dwarfs Mine Train.
