Makes sense. It’s my picture (taken Monday and shared here a few minutes after I took it)— and I took it because there were actually 5 people up there (hard to tell but there’s a woman and a guy in a black cap almost entirely obscured by the front 3) walking around for a bit between Avengers Assemble shows. They seemed to be focused on the outside space on the terrace so I would have said it looked more like planning a different show than necessarily planning an attraction. Of course they may also have been surveying inside before emerging out on the balcony but I would not have been able to see it.Like others have said and I have seen it time and time again. CMs generally have no inside knowledge of what is going on that is not officially released. Most of the time they get their information from FB groups or other CMs and just repeat it. Then more people repeat the rumor because a CM told them so it must be true. If this is true I would think we would of seen permits by now.
Also if true Disney PR would of taken the opportunity to hype up the upcoming attraction and officially announce a last show date for Dr Strange. If I remember correctly bloggers caught the calendar showing no more shows and then Disney made a statement to local news about it with no official reason why.
That picture with the employees to me just looks like stage techs (their normal costume is all black) discussing with a show director regarding the stage.
