Well, they'll be re-releasing older areas anyway. The Frostval Labyrinth will return as they're seasonal, but we can expect a lot of newer things from year to year. I just hope they don't make us grind in the same dungeons again since it was boring, particularly when they made the Frostlorn items require grinding in those dungeons. Would be nice to see newer dungeons for Frostval, so then it would feel like a different experience. New items will always be a possibility of course.
