Our online store has them virtually "back in stock" so you can pre-order them, but retailers should be able to start getting pre-orders as well so don't be shy, take your campaign to a new level by taking it below!
So, whose going to start a "The Deep" web-ring? Seriously, though, I would hate to see the momentum for undersea games, caused by the release of "The Deep", begin to fade. I have message-boards set up at lobi.com/bpaa (my game is message-based). Perhaps I shall set up a new topic for discussion of undersea D&D. I also have a java chat room over there, if the momentum builds enough to warrant scheduling regular meetings.
