As an added data point: On Saturday I saw my car at the SC and it was being prepped for delivery (still don't have it, but should be prepped by end of week).
As of last night, I still had a delivery date of February. This AM it changed to TBD on the web account and my Tesla app now shows "Schedule Delivery Appointment" with "Start" grayed out.
Supposably my car should be ready to schedule delivery imminently (hoping for today or tomorrow), so I think we can deduce generally that a "TBD" deliver date is a more advanced / better state in terms of delivery timeline. But this is just my reverse engineered interpretation of the black box that is this whole delivery process!
