Just to clarify... the ride was scheduled to shut down that Sept. The building was to be gutted and the ride rebuilt with an identical track layout. They knew there were structural issues with the track, but thought it would last through the Summer.
The above mentioned morning inspection revealed damage that could have been fixed, but would have taken time and money, and then it could have happened again anyway. So, they shut it down about 5 months early. (which resulted in a longer overall shutdown since nobody was ready to start the work at that time)
I hadn't heard that there would be any new effects on the ride itself, but I wouldn't be surprised if there is a new soundtrack when it re-opens, along with the new queue/loading areas.
I thought the new theme was posted somewhere, but I honestly don't remember what it was.
