Good question! But one that seems born out by many reports here over the years that this or that show didn't seem to make many changes beyond cosmetic details in between an out-of-town tryout and Broadway. This seems to apply even to shows that didn't get overly positive reviews out of town.
The reviews for PRETTY WOMAN were pretty dismal, but, aside from a new leading man (a change that did not come from the creative staff), I'm betting that what we see in New York will bear a striking resemblance to what was seen in the tryout.
