Since the production is going to LA on Dec 10 for four weeks, the Nov 30 closure on Broadway seems definite. That's only four months from the date of the first preview on July 31 (or 5 months if you count the LA stint as well). The Encores production had 27 cast members and 26 orchestra members. That doesn't seem like a good recipe for recoupment, but the producers have the same information I do and apparently have a way of making this work financially.
