At Epic Universe, just on opening day there will be:
In Dark Universe:
An e-ticket Monsters dark ride, like Forbidden Journey but all physical sets instead of screens and with the benefit of 14 years of technology improvements.
A spinning family coaster very similar to Cosmic Rewind featuring show scenes and a massive Werewolf animatronic.
In How to Train Your Dragon:
A really fun looking and well themed family coaster with a water section.
A competitive shooter/boat ride hybrid with water cannons.
A high capacity flat ride, not super interesting but will add lots of kinetic energy and take a ton of guests.
In Super Nintendo Land:
Mario Kart: one of a kind, really fun, and extremely re-rideable.
Yoshi, a cute slow moving dark ride.
Donkey Kong, a highly themed coaster with dark ride sections and a completely unique ride system.
In Harry Potter:
An E+ Ticket ride. Details are light right now, but it's being billed as "Universal's answer to ROTR". IMO ROTR is missed potential, and from the way they talk about this ride and the budget it had, I could see this being the literal greatest ride in the world, or at least top 5.
In Celestial Park:
An incredible looking coaster, likely on par with Velocicoaster with completely original elements.
A carousel, just a carousel but definitely a cool looking one.
This isn't mentioning that each land will have walk-around characters and meet and greets running from opening to close, constantly. Also not mentioning playgrounds, all of the stuff there is to do at Nintendo, the world class theming in the lands, and the fact that they all have dedicated full size restaurants.
It really seems like there will be something for everyone at Epic. I also really can't wait for the HP dining hall and Luigi's Mansion additions
