Now, this is a more interesting discussion.
BMG partners with Universal and Luxor for their shows, but both are in highly touristy areas and I can see them staying. They own the theater in NY outright. I could see Chicago and Boston closing, though. Also, Orlando is the "largest" of their shows at over 1000 seats. The Cirque comment also applies to Drawn to Life too.
As for the "half capacity" notes, the show is designed to run at both full and half capacity, with a curtain drawn to cut the back half out if necessary. So the show can financially work at half capacity. Plus the show is doing better now than it was pre-Potter.
After thinking about this overnight, I think there's someone in Ops who'd like to take over the theater but their "want" doesn't mean anything if there's no show to run in its place or if CityWalk and the rest of management want to keep the show (let alone any contracts they must uphold).
