Just took the Undiscovered Future World tour, and was at the part of the tour that is behind the scenes at Test Track. Our guide was showing us the new cars, and giving us some details on the new ride. She said she wasn't sure when the new Test Track was slated to open, but just then, one of the Test Track Imagineers walked by. She asked him when opening day was, and he said "in 44 days". She got all excited to know this info, as they didn't know it yet in guest relations where she worked. Just FYI, in case anyone is interested! We thought it was kinda neat to hear the info from the Imagineer that is working on the new Test Track.
