New rumors:
@CarouselOf on Twitter is reporting that the Magic Eye Theater in Epcot looks to be closing soon. It apparently won't be reused, but instead demolished.
@CarouselOf has also said details about Carousel of Progress updates should be expected this coming week. "Carousel Of Progress will be receiving a extended downtime for a better show experience." "It's [extended refurb] confirmed, they already have the construction company contracted out. They need to fill the permits and confirm some people from WDI. And the people from WDI are on the programming and control side of things because they haven't assigned just 1 person yet."
Finally, the same source has said that Speedway will go down for an extended refurbishment in a couple of months time so that track can be re-worked and re-done so Tron construction can begin.
Now, I don't know how trustworthy @CarouselOf is, but they do seem to know their stuff. We'll have to wait and see...
