Don't worry, the spectacular isn't going away, but recently, I noticed a change in the closing narration - in my opinion, more fitting for the ending to a good day at Disney:

"Ladies and gentlemen, the entire Epcot family thanks you for having been with us for 'Illuminations: Reflections of Earth', presented by Siemens. We hope that your visit to the Walt Disney World Resort has been a truly magical experience for you and yours. We wish you a pleasant evening and a safe journey home. Thank you and good night." [cue "Promise"]
