Brayden of Mickey Views is the new source pushing the rumor. What he heard was as follows
Frontierland is cut in half, the section with Diamond Horseshoe, Shootin' Arcade, and gift shop will be reincorporated into Liberty Square.
Country Bears and Peco's Bill will be combined with TBA to make a New Orleans Square.
Country Bears will receive new electric AAs and the show will be changed, possibly to vacation hoedown with some modern references.
Peco's Bill is changed to Tiana's Place, and also a possible dedicated window to order beignets.
Big Thunder will be kept the same, except now part of a vaguely desert/southwestern themed area with the Coco attraction.
Encanto's ride will sit between Coco and Villains, it may or may not be directly part of the "desert" land.
Villains Land will be situated between Encanto and Haunted Mansion, providing a new path for people to walk all around Rivers of America, to do this they would most likely shorten the river's path
