Have you heard of anyone not being in the 1-500? Pretty much everybody could see that on the Web regardless of their order number, right? Or I'm mistaken?
As an experiment, I created a new account with a different email. The products page does not allow the new account to order a 1-500 unit. So only people that pre-registered back in April can make orders for the first batch.
It could be that I'm blowing this out of proportion, but IMO this is a big deal especially for a company charging $7000+ for their products.
