If our lord and savior, George Carlin, hasn't returned to bring us all home to his heavenly kingdom in five years, I predict WDW shall still be going strong like it is today. Water Taxi's and Friendship Boats may have replaced monorails and resort buses as the primary form of transportation by then, depending on how much of Florida is underwater. Gondolas won't be a thing, as we all will remember with heavy hearts the tragic zombie fire lightning smelly passenger apocalypse which disabled that option back in 2020. (A brief moment of silence for our kin and loved ones still stranded in mid-air by then.) Many offerings will continue to increase in price over the course of those five years, as to be expected. Attendance at MK will reach an all-time high, especially after the election of U.S. president Winfrey, and her inclusion in HOP guaranteeing any visitor to that attraction a brand new car. Meet and Greets with new characters from Toy Story 6, Frozen 4, The Great Mouse Detective live-action remake, and Star Wars Ep. 11: Where Do We Go From Here? will be present throughout the parks. Tomorrowland Speedway will be considered old-timey and relocated to Frontierland by then, as most humans on earth will have forgotten how to operate any vehicle thanks to driver-less cars. Ownership of the parks will remain as-is, though depending on how careful or careless we are with sports almanacs today, it could change hands to Biff Tannen by that time (I've seen it happen before).
Just my two-cents (which by then will be worth 1.2 cent).
