I just wanted to add something to what CPD said about this show being a limited run. IT has nothing to do with there not being a name in the case. There never has been a Disney show that has a name as an incentive to buy tickets. In all of Disney's Broadway shows they use the popular movie that is based on as the reason to buy tickets.
In any event Broadway was never originally in the cards for this show. Just like the stage musical of Aladdin that opened up awhile back in Seattle, Newsies was done as a precursor to amateur productions with no intentions of Broadway. However, Disney realized that they would get more money on licensing the show if it has played on Broadway. So, since they got good reviews across the bridge in New Jersey, they decided to test things out on Broadway. If all goes well, they will extend. If not, then they will still make money on amateur licensing of the show.
