I'm getting a bit concerned. There should now be a big batch of invites every week. Headliner might not be the only supplier issue striking once things are ramping up.
Everyone there is a chance invites have not gone out, but I would also say there is a chance they have. The active members of the boards represent say 100 reservations outstanding if that. The number of estimated US reservations for this timeframe is roughly 15 thousand or so. Basically saying representation could be under 1%, so very possible invites are going out just not to anyone in the represented group on the boards. Last VIN progression was in the 8000 range if I remember properly, so at 1000 per week they still have a few weeks before needing to get more VINs.
From what I can tell, things are divided into a few groups:
Employees (this appears to be completed for the "first production" model)
Current Owners in CA (two waves of invites)
Current Owners outside of CA (seems to have been ongoing)
There has been a pause since Jan 4th.
Could very well be that the are starting one of the biggest groups for the next wave, which would be non owners, day 1 reservationists (likely just in CA) If they are catching up deliveries and ramping up to start true mass deliveries, a pause while they amass inventory and fulfill what they have configured already. I think people are expecting this to be a linear process, it's going to be fix bottle neck, new bottleneck appears. Until they hit full throttle (10k a week) it's likely going to be wave of invites, wait. Tesla will check the inventory, see how the numbers look, then send out another wave. Time between invites isn't going to be every 7 days, it'll likely vary as the size of invites steadily grows. The ramp is going to be a set of stairs to big numbers, not a smooth line.
