I'm in the same boat of confusion. I still booked for December 17th at 6:15pm. Previously the calendar said that Wishes would be at 10pm (same time as park closing). Now when I go to Disney World's web site to look at Magic Kingdom's schedule for that day - I get the following message: "Activities at This Park/Destination cannot be displayed at this time, for the selected Date". I assume they will change the time of my ADR for Wishes Dessert to a later time that is at least an hour before whenever they decide fireworks will be. I'll just try to keep calm until I get closer to the date.
