Tesla is not great at outside communication (dissolved it's PR department) and their internal communication is limited to need to know only. I think some SAs have better relationships with the manufacturing side than others. That being said my SA told me recently that MYP production should begin at Fremont week of Thanksgiving. Delay has been due to focus on Europe and Asia deliveries to boost sales this quarter. Likely we won't see any major shift in production until December is my guess seeing as how the MYP demand is not nearly as large as the new M3 or MY LR.
That would be crazy. That would mean that they were taking reservations since mid September, with 4-8 week window, with no intention of producing or delivering cars.
