Well, the other site with the pre-orders is all closed, right on 24hrs.
Based on that, they had zero idea how much stock was coming in as each card should have in my view close on a set number of pre-orders for said card, but I have been tracking all cards that opened for pre-order, and all stayed live right up to 24hrs.
Sounds like a nice interest free loan they wanted, but good luck to the guys who ordered as I doubt I have the patience keep looking at my queue count if I am getting closer to zero.
