So I'm one of the folks who ordered one of the soon-to-be "ultra-rare" SR Lariats. :)

I ordered in Wave 2. Dealer accepted minutes after I submitted. Got the confirmation email from Ford.
On ford.com, my order shows the number 2 "Place Order" as "In Progress" and blue.
I do have green check marks below on "Order Sent to Dealer" and "Order Accepted by Dealer".
