I can confirm as well. Delivery now scheduled for 12 PM CST next Friday and VIN appeared around 2 PM CST today.
Very small sample size, but perhaps they are finally standardizing this and getting away from chasing down VIN 2-3 days before scheduled delivery for those still waiting. If it weren't for my delivery being rescheduled from Monday, I'd be stressing as I need executed MVPA to wrap up financing, which was dependent on the VIN.
Sample size of one, I have home delivery scheduled less than a week away (was 9/24 now 9/26 on my request) and still no VIN or purchase agreement (MVPA). Of course in my case the VIN doesn't matter until the car shows up since I'm not financing. I'm also in SF bay area so they probably access to more vehicles to swap in at the last minute.
