I emailed him. He replied.
Basically they're getting built and shipped as quickly as they can - based on item, time ordered, and your location.
Here's his reply:
Jason,
We're working hard to get as many units shipped as quickly as possibly. We're shipping in the sequence the order was taken for the specific configuration. No one ordering the configuration you've ordered in the country you live will be shipped before you.
We did complete more of some configurations than we originally predicted for delivery tomorrow. These customers would have been quoted longer delivery times initially. This is likely what you are reading on the web.
Thanks for your patience. We will get you the product you ordered as quickly as we possible.
