I am in the same boat.
I have pre-ordered and upon initiating checkout during the purchase process, my impulse window went white and i was left without confirmation. I can select to view cart in the top right corner and it takes me back a step, potentially checkout again.
"Your order contains at least one pre-order item. You will only be charged for the items in your cart that are available at this time. Your pre-order will be saved in our system, and when the product becomes available or beta access is granted, you will be charged and notified by email."
I assume we just wait, unfortunately. 32 years old and I gotta close my eyes and imagine tomorrow is christmas. Effin Phooey.
