Printers have already been delivered to the first, second, and third tier beta testers.

As of the latest update, printers for the first (Jul), second (Sep), and third (Oct) tier version one have been "pushed back" but there's no indication by how much. I believe this is the first schedule push back, so I wouldn't expect it to be a massive one. They did not sell-out their third tier version one, so I would assume anyone who orders from their "coming soon" store would expect delivery shortly after, or at the same time as the third tier version one Kickstarters.
