Definitely have my fingers crossed for some kind of quest with a daily component.
Like everyone else, that sick screenshot that Dusty posted definitely gave me hope for what's to come of the Castle. I would love to see a room with castle-themed furniture. Maybe a dungeon area with "escaped prisoner" baddies as well? (which could tie into a daily quest)
Whatever the case, it looks like the Castle is getting a long-overdue and well-deserved overhaul.
Here's hoping for a Castle that deserves to be in the centre of the map.
