There are many Rumors of Magic Kingdom's Expansion or an Overhaul.
My opinion is that I would like to see Magic Kingdom's Expansion for a Major Overhaul, like starting in Adventureland I would like to see either Swiss Family Treehouse gets a retheme into Tarzan's Treehouse or The Lion King E-Ticket Attraction based from the 1994 Animated Film. or next to POTC & JC, I would like to see the Shanghai Disneyland's Pirates of the Caribbean: Battle for the Sunken Treasure, and Moana E-Ticket Attraction, while in Frontierland I would like to see Nature's Wonderland from Disneyland since used to ran from 1960-1977 but a new version, also Woody's Round-up Whip-Ride from Shanghai Disneyland or the Pocahontas ride in the expanded area. In Liberty Square Haunted Mansion shall stay the same but uses the John Debney's 1992 Music Orchestrations from Phantom Manor at Disneyland Paris, all the rest of the sounds and voices shall stay original. In Fantasyland, I would like to see the new attractions from Fantasy Springs like rides from Tangled & Peter Pan, Pooh's Hunny Hunt, and Enchanted Tale of Beauty and the Beast from Tokyo Disney Resort, even Wandering Oaken's Sliding Sleighs from Hong Kong as a Frozen Mini-Land, and the Major Overhaul of Peter Pan's Flight 2.0 based from Shanghai Disneyland's Version, It's a Small World shall stay the same but uses the John Debney's 1992 Orchestration Music from Disneyland Paris with 40 Disney Characters included too. and last but not least Tomorrowland, we know that TRON is coming to that park, the only retheme attraction in Magic Kingdom is Buzz Lightyear gets a retheme into the Shanghai Disneyland's Buzz Lightyear's Planet Rescue in Walt Disney World's Magic Kingdom, and Main Street Electrical Parade should get a Dreamlights version from Tokyo Disneyland Version in Walt Disney World's Magic Kingdom.
Let me know in the comments, and let me know me what do you think of the idea.
