Chapek is plain wrong too.
There is a precedent for a theme park behemoth holding an IP catalogue almost as good as 2019 TWDC and not using it in their parks: TWDC 1955-2015.
Chapek is simply lazy, he thinks sitting on the best IP staple provides him a quick hack to the best parks, that it provides an unassailable competitive advantage. Disregarding that the true 'Disney' difference in the theme park business has been quality, immersion, sentimentalism. And hard work. IP, by contrast, has always been the shortcut of precisely the non-Disney parks. How many Superman coasters aren't out there in wannabe parks?
