I got this reply in an email asking if they had any updates
Dear Ian,
Thank you for your email.
It is not possible to provide a more specific date as the information you can view on your order status is the same as the information available to myself.
It is not possible to change the delivery date. We're working hard to get as many units shipped as quickly as possible. We're shipping in the sequence the order was taken for the specific configuration. Customers ordering the configuration you?ve ordered in the country you live will not be shipped before you.
We did complete more of some configurations than we originally predicted for delivery today. 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 possible.
