Again, as I've said before here, the existing SNW is *only* 8 acres. It's relatively tiny., especially if they want it to be the "cornerstone" of the new park. It makes sense to have Pokmeon and Zelda or whatever else they have planned to go along with it.
And it's not like the popularity of Pokemon or Zelda will wain the the coming years. While this is an unpopular opinion, they would be prudent to hold onto one of those popular titles as an expansion ~4-5 years after park opening. They almost certainly will. It's just a matter of which IP they'll likely hold back from Day 1. Sad, yet humbling reality.
I have heard Warner Bros. WORLD is pretty FANTASTIC.
Just sayin'.
I have to wander if WB ever sits back and wishes they would have jumped in the Theme Park arena back in the 80s, instead of Universal. To be completely honest and non-biased, WB has a much more extensive catalog of IP than actual Universal IP. And one that bodes well for a theme park. Granted, most of these are shoehorned into other parks, or licenses, etc. But think of this lineup:
Harry Potter/Fantastic Beasts
DC
Lord of the Rings/Hobbit
Lego Movie (if no Legoland)
Godzilla and Kong
That alone would be a park better than Universal-exclusive IPs in both USF and IoA combined (no marvel, kong, HP, toon lagoon, Seuss, Transformers, Simpsons etc). Universal relies on external IPs quite a bit.
Lesser "tier" but fully capitalized properties of:
Dr Who/The Matrix/Blade Runner
Sherlock Holmes
Pacific Rim/Edge of Tomorrow
Ninja Turtles
Mad Max
Scooby/Jetsons/Happy Feet/Looney Toons/Tom & Jerry
Seasonal:
It/The Conjuring/Exorcist/Misery/Nightmare on Elm Street/Friday the 13th/Final Destination
Elf/The Polar Express/Christmas Vacation
Walk Around Characters:
Austin Powers
The Mask
Dirty Harry
The Griswolds
Striptease and Magic Mike, depending on your flavor
Their category is expansive. But instead they license out a chunk of their properties- some poorly (looney toons, DC), some incredible (HP) and some acceptable (Kong, HHN)
