I just spoke with my SA, she called, and also with a sales person at my local store, Coral Gables, FL.
Both say the identical thing.
My car is now in transit and is due to arrive at Coral gables on August 25. It then will go though the now standard about one week process fo updating and inspection. Delivery can be September 2, but they will 'have flexibility' so I can choose any date after they have completed the Service Center QC and update processes. One fo them volunteered that it will have "Active Noise Control and significant FSD enhancements", which will be part fo a software update it will receive prior to delivery.\\
All of that si so detailed and specific that I now choose to believe it! I will have my:
Plaid.MCR.creanm.FSD.19" in a couple of weeks.
FWIW, this will be my third MCR in a row.
