Well, if you want to get technical, Mickey's Twas the Night Before Christmas cannot be shown in MK since they tore out the theater.
Interesting observation. No more theater, no more show.......
They wanted to get rid of Twas. It was a monster to run, and VERY expensive. Full band, equity performers, technicians, costuming, cosmetology.
If there was no theater...hm...they wouldn't have to do the show anymore.
My "educated" guess is that you'll never see remnants of Mickey's Twas ever again. I can guarantee they won't move it to Studios. They have SoDL...they don't need anything more to bring in guests. They won't up the attendance by putting a Mickey show in. And they know that.
