I've been on the list 2 days in a row now and have missed out on both opportunities.
Today being my lucky day I paid close attn to the pattern and noticed that the email notifications were sent out at 3pm PST both days. Decided to refresh their site today at 3pm and voila, In stock...
Sold out in 2 minutes so I say jump on it tomorrow and see if it's the same situation. Hope this helps.
