I know a thread like this was done a while ago, but I think it disappeared into the unknown realms of MiceChat.....or a double-digit page. ANYWAYS...
Here are my thoughts on what Disneyland could do if it really wanted to create a true "nostalgic" sense. These are suggestions for the "nostalgic" side of things, not the "new additions" side of things.
--Main Street Electrical Parade returns
--Updated 0 Magical Years
--Barker Bird in the Tiki Room
--Jungle Cruise receives striped covering
--Pirates is given a new story (looking for TREASURE, not JACK)
--Hatbox Ghost returns to Haunted Mansion
--Country Bears Meet 'n' Greets in Critter Country
--Golden Horsehoe Revue Tribute returns
--Davy Crockett Meet 'n' Greet
--Fantasyland Skyway Station becomes "Skyview Terrace", a new snack location (the food carts below will have some of their merchandise moved here)
--Matterhorn Climbers and Band
--Captain EO will play its final performances
--New daytime parade: Worlds of Fantasy (Float for each land)
--Updated "Remember..." (but not too much).
--All culminating with the demolition and crumbling of Innoventions
