Congratulations of reaching D1 status! Welcome to club of wanting to habitually check the Insite website in regards to new order updates. Vehicle arrival delays depend on many factors... Some I read or heard about include limited production with bright white inaugural edition SRT8's, stripe overlapping, and manufacturer delivery costs drama with Allied Shipping.
Murphies law pretty much takes the steering wheel when it comes to the delivery ETA's. I hope everything work out so you can be in the US before the delivery arrives. Good luck!!
LOL!! In my humble opinion... I think you should be fine if you recently hit D1 status on an inaugural edition. From what I have noticed online... non-IE 392's are being released quicker for those who placed an order from the dealership.
