The IP mandate is, what, a decade old by now?
The die is cast.
For weal or woe, (almost) all new attractions will be IP based. Current attractions without a Disney IP will always be 'in danger' of being rethemed to a Disney IP.
What's surprising is that some people are still surprised by this.
Sure, it's OK to not like it. But, if you want new attractions, especially in a park that's in need of new attractions, you're going to get one of Disney's top ten IPs.
I trust attempts will be made to make it 'fit' the park/land. How successful that will be is yet to be seen. And each attraction will have its own success rate.
And until one knows the actual 'story' of a new attraction, one won't know how successful it will be. But if one wants to yell at a cloud or a black box... knock yourselves out.
an IP installation does not equate to automatic bad fits.
What it does is under current management, it runs more the risk.
Declining by degrees.
One can be ok with 1920s-30s New Orleans in Frontierland. One also can't be surprised why the world's most famous theme park would be seen as bending on that one.
Which means one can't be surprised to see the doubt that Indiana Jones can be trusted to keep the property integrity while keeping integrity of the theme park when they have shown integrity is already expendable for cinema and tv IP.
