All 3 of those rides look better than most of what we have in both US parks. We need some more awesome tech here, like Universal did with the Harry Potter ride vehicle.
After years of non-investment in US Parks, spending has now been restored to late 90s levels. Pandora in May. Star Wars land on both coasts in 2019. Toy Story land probably late 2018 early 2019 alongside Toy Story 4.
Rumored replacement for Stitchs Great Escape at Magic Kingdom amongst others lead up to a nice state for the 50th anniversary of MK/WDW in 2021
I probably won't make it back to WDW until sometime in the next decade but big-budget park additions are always exciting.
I'm kinda torn on Walt Disney World as a whole right now. The wife and I went to Disneyland for the first time in our lives on our Honeymoon last month and as much as I hate to admit it, I do think Disneyland has a slight advantage over WDW in a few aspects. (Though pales in comparison in others.)
The dismal state of Epcot is the most depressing. Hopefully they start doing some major renovations soon...renovations that don't involve shoving more Disney IP in places they don't belong, anyway. (I still mourn the loss of Malestrom...I'm actually wearing my Malestrom shirt today at work.)
I feel your Epcot pain. Bob Chapek, chairman of Parks and Resorts, said he's telling Imagineers to dream big to fix Epcot and that changes and additions will be Disney, timeless, relevant, and family friendly while remaining true to its original vision.
Time will tell how true that is but recent updates in the park show they know it still exists and needs work.
