Not just your imaginations. A quick search of the DPB found this blurb from a post on 08/25/19 (emphasis mine):
In 2020, following the limited-time run of “Epcot Forever,” the new “HarmonioUS” will debut as the largest nighttime spectacular ever created for a Disney park. It will celebrate how the music of Disney inspires people the world over, carrying you away harmoniously on a stream of familiar Disney tunes reinterpreted by a diverse group of artists from around the globe. “HarmonioUS” will feature massive floating set pieces, custom-built LED panels, choreographed moving fountains, lights, pyrotechnics, lasers and more.
Seems the show title isn't the only thing that's been downsized in recent months...
