You give a realistic opening date.But... Does it matter? Disney has a long history of opening delays, technical malfunctions and operational blunders going back to 1955. Its just part of the business.
And for the people who have been on the ride and enjoyed it, Disney has met all the expectations and exceeded then. Conceptually, does it really make sense to keep the ride closed and disappoint a larger group of people than opening it to the few?
