If they want to get rid of Frontierland, why did they just redo the Country Bears and still have it be country/western music? Why are they making a western themed lounge? Why'd they say that Cars would specifically be a part of Frontierland? They even made a Front-tire land joke. They also just added some new animated windows to Liberty Square, and with HoP down for refurb it'll be here for at least four more years.
I'm against the removal of the rivers but I don't think Frontierland itself is going anywhere. Liberty Square too, it'd take way too much money and effort to redo both those lands, especially when everything new being added to them matches the theme they currently have. It'd make no sense to spend the money on these projects only to then change the lands entirely and demolish/redo everything in them. Frontierland at least is just being redefined as "the American wilderness" as a whole instead of just cowboy-related stuff. I could see Liberty Square becoming Sleepy Hollow, keeping all the same buildings and just replacing HoP with something, but even that's not likely in this current climate. Disney has "switched sides" effectively, given all the stuff that happened with Win or Lose (which is a great series, but the changes to characters last minute certainly killed any good will the public has) and their policy changes in terms of hiring and such, so I don't see a world where they remove anything "American", especially when doing so would likely make them a target. DeSantis was annoying enough to deal with, but having to deal with the whole administration? Disney doesn't want that, so they're gonna appeal to them instead of actually having a spine. Frontierland and Liberty Square aren't going anywhere anytime soon.
