It's a little frustrating that we keep having to go through this, but let's give it another whirl:
This show was conceived, adapted, and produced specifically for the Public Works program. Not only are there no plans to bring this production to Broadway, but the way show is done now, it CAN'T be done on Broadway. In fact, the whole reason Disney even allowed Public Works to do the show is because they had no plans to use the property to make a Broadway show of their own (this was told to me by a very reliable source, though it might be an oversimplification).
And hey, maybe Disney will change their minds and realize there might be money in bringing the property to Broadway. But if that happens, it will not be affiliated with this current production, and there would likely be an entirely separate development period, with a different production team, etc. It could even very well be an entirely different adaptation.
OR they could license out this version of the script, and MAYBE there will be some high profile production that Disney decides to put some money behind, and eventually bring to Broadway. But again, that would be sometime way down the line.
Another possible way we might see this production again is if they bring it back for the annual Public Works slot next year, or some year after that. Kind of a "back by popular demand" sort of thing.
