I just read on another thread that there is a rumor that the whole Land pavillion will be going down for rehab early next year for final preparations for Soarin'. The rumor is when this happens, WOL will open back up, which makes sense. They did the same thing with Horizons. It was closed down, seemingly for good, but then they decided to get rid of World of Motion and build Test Track. They re-opened Horizons during the building of Test Track and then as soon as it was opened Horizons was gone for good. Now, my guess is they won't tear it down unless they have definitive plans for replacing it. That way they can use it in a similar situation, much like they did with Carousel of Progress. So you may get to see it again, but I don't think you'll ever be able to plan on it.
