My dreams are really coming true. I thought that Universal Studios couldn't get any better after they added the Wizarding World of Harry Potter to the mix, but Nintendo and Universal have officially signed agreements to work together to create some awesome rides and attractions based on Nintendo's games, characters and worlds.
That means Pokemon. That means Zelda. That means Mario Kart. That means more things that I can list to be possible be excited about.
Here are some rides/zones I thoroughly expect to be created at some point, because they'd definitely be among the most popular:
Rainbow Road Ride
This course is easily the most memorable of the Mario Kart courses, which means it needs to be made into a ride. Imagine if they made it so you "fell off" the road, like you do in the game! Or, imagine that they make it a Mario Kart ride where you can pick your course when you get in line, so it's like a few different rides all in one attraction. Imagine the possibilities!!
Duel Racing Coasters
Samus Aran + Captain Falcon = dueling/racing coasters. MAKE IT HAPPEN.
This girl's got some ideas too, though I have to agree that maybe some are a bit too...unrealistic.
