Every time third time (or so) that I edit the OP, it goes into "Approval Pending" so I am going to stop editing for the day. If there are additional time stamp submissions, I will try to do them in a batch over the weekend. I think we have enough data points to be able to track where the "invite to purchase" email line resides (once they start flowing).
I remain unclear about whether they will start shipping next week (per @EVGA_JacobF's tweet) or around December 15 (per the product page). Prior to today, I had understood that they were shipping "mid December". Hopefully clarity will follow in the hour to come.
Thanks to everybody for participating in this thread. Hopefully it provides the community some utility over the days and weeks to come.
Have a great weekend!
