I know others will disagree, but I do not believe Broadway would survive at Disney Springs. I don't want to hijack the News thread, so I won't get into lots of analysis. But, Disney Theatrical wouldn't be keen on losing part of their New York and touring production audiences to Disney World.
There's also the problem of the theatre. The La Nouba theatre is a thrust stage and all of the Disney Broadway shows were created for proscenium stages. That means they'd have two options. They could completely re-work every show to fit a thrust stage. Or, they could build an entirely new theatre. Both of those options are wildly expensive. And, they aren't even sure bets.
Guests already have sticker shock when it comes to vacation prices. Convincing people they need to spend an extra $100+ per person for a two-hour show is an uphill battle...especially if they can go see elements of The Lion King and Beauty and the Beast for free at the theme parks.
Finally, Orlando already has a state-of-the-art in Downtown Orlando: The Walt Disney Theatre. If Disney tried to pull all of their touring shows out of their namesake theatre to put them at Disney Springs, the local community would not be pleased. That's a PR nightmare not worth invoking.
