I wonder if plans changed or WrestleVotes were wide of the mark? If she doesn't return on RAW tomorrow then the next live show they are running, on either brand, is Dec 27th, which I guess is still technically 'imminent', but they could have put this post out closer to the time if that was the date they were expecting to perhaps save a bit of face.
Probably looking more like Netflix at the stage.
Edit, just realised she did return on the post Xmas Dec 30th Smackdown at the Amalie Arena, Tampa, in 2022 to beat Ronda for the title and that is the same arena on the Dec 27th show, so that could be a symbolic place for her return.
