This is not true.
There wasn’t any promises or intentions to drop a song, video, & album cover. As a matter of fact, she was planning to unveil things on tour including the new music & while on tour start to phase in the new project.
Honestly, the project was to give new material to her tour & fuel more sells. Janet has had music in the chamber since before, during, & after SOTW tour.
At this point, she could drop an EP of new music/unreleased music. With some graphics & content to amplify it...that would just hold her over till next year.
