Here is the last email text I received direct from Tesla when I did my best to attempt to attend the "ceremony" (my words) on the 29th:
"Thank you for continued enthusiasm and support for Tesla!
At this point, we are not planning to hold a ‘Founder’s Ceremony’ at Fremont. We are delivering our first cars on this date, but there will be no official public event.
Should this change then I will of course be in touch."
IMHO, a handoff of key fobs to several Founders is all that I expect to see by video. 2012 news links that I have previously posted of the two Model S handoffs show only the Fremont employees and one Founder person getting their Model S early on and then another event where the first cars were rolled out of the factory. This was back in the days when each Tesla Model S would be delivered personally. Unlike the many "invited" events I have enjoyed through the years, no invite appeared for me in 2012 for those "handoff" events, even though I had a Signature order.
Since the X Reveal event in 2012, I have mentioned to Tesla employees my hope for a factory celebration many times, but in recent months the comment from long time service center individuals was that normal deliveries at service centers were being planned for Model X. Local delivery management recently mentioned to me personally that extra time may be required to make sure that the first vehicles are perfect. Only one promise was made, that my Model X would be delivered before the end of the year. Being in the first configuration group for Model X Signature, IMHO, it should be sooner than that.
At this point, I absolutely want Tesla Motors to take their time to get the early VINs perfectly assembled and tested before delivery. By NOT having an event for the first deliveries of Signature X, Tesla Motors would have the flexibility they need to not rush and let Elon double check the quality. Once those first vehicles are perfect, if they want to schedule a last minute factory handoff, I would attend in a moment. But at this point, no "change" has been mentioned, so delivery at a local service center (that currently appears in "View Profile - Pick Up") is what I can expect.
