Here's some food for thought. If TDO markets the 40th as some 40 years of memories or 40 years of magic, I wonder if any rumors we had from earlier in the year would have the Carousel of Progress closing for a new ending that would open by the 40th with either a new year set off into the future or a retro future that would compliment the theme of nearby space mountain.
PoTC, HM, Space Mountain, Jungle Cruise, Hall of Presidents, Peoplemover, and It's A Small World have all gotten some kind of recognizable refurbishment, all within 2005. Other than the Tiki Room, the Carousel of Progress is the only Disney classic that hasn't been significantly refurbished. Can you even count swiss family?
