According to the firm that handles NYTW’s PR, the production begins previews in early May toward a June 1 opening. If the 6-7 weeks theory holds true, that would mean tickets would go on sale in late March/early April. Given that they have been heavily marketing subscriptions on the basis of getting access to tickets to this, don’t be surprised if the production is also heavily sold by the ticket it goes on sale to the general public.
On another matter, is Heidi Schreck no longer associated with this production?
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
