I think this means I win...
I'm starting to think WDW won't rename the park. They've been doubling down on the Hollywood theme for the park's public spaces. And they've been doubling down on putting in IPs from studios that Disney owns. Based on that information, you would think they'd call it: Disney Hollywood Studios.
If the favorite worlds are from the various Disney movie studios and the public space is Hollywood, then the best description would be "Disney Hollywood Studios."
