Here's my opinion on Mario supposedly being moved to the third park for anyone who's interested.
I'm generally pretty happy with this rumor for a few reasons
-the kiddie problem
As discussed before, USF has very little offerings for kids younger than five, and if they're trying to compete with Disney, this is a problem. KZ is sizable, but even with it USF has very few things for kids that young to do. If Universal were to completely bulldoze all of KZ one day, it would leave the park with pretty much one attraction for <5s. Uni is smart, and they will see this weak spot, and change strengthen it, using the new construction to create many kiddie attractions within Mario-land. That's just not what I want for the land, Mario appeals to ALL ages, from the older folks that played DK in the arcade, to the 10 yr olds playing Odyssey on their Switches. These necessary kiddie areas would ONLY appeal to <8s, and I feel that would take away from a lot of the enjoyment if you're older than that. I would rather it go in the new park where things like Hello Kitty and Minions can make the necessary kiddie areas and Mario can be left to more or less appeal to the older crowd, 10+ for the most part. A workaround to this is that USF could use one of its expansion plots, MIB or I think there's a Simpsons one?, to make new kiddie stuff, but I don't see them putting the only kiddie area in the back of the park, and it would be so much easier to put it in with Mario-land, I can't see them not doing it.
-buisness sense
I'm a fan of the way Universal make more thrilling rides, and rides that can be much more mature than Disney attractions, so I like to see them succeed so they can make more things that I'll enjoy. That said, this decision would just make sense if a 3rd park is on the way. Mario has the most pull out of any IP Nintendo has, and having it at USF, the park with Minions, F&F, Transformers, some of the most popular IPs right now, and also the main park people think about when they think "Universal", the new park needs the Mario IP much more than USF. USF getting SOME form of Nintendo area would make sense as a bit of a sneak peek of what Universal is doing with Nintendo, with signs that say "Enter the warp pipe and head over" advertising the 3rd park from USF, that will make bank.
Reasons I'm not a fan of this decision
-it's been a while
I do share in the sentiment that it feels like we were soo close to finally getting the SNW we were promised years ago, and Universal hasn't made a themed land since 2014, was really looking forward to this.
-there goes my money
Ticket prices boutta go up, not too excited for that
My official verdict: ok cool
