The sky is not falling. Before the recent prognostications, the expectation was to produce a Model 3 by end of 2017 and to go to town in 2018. Well, they've produced about as many Model 3s already as Model Ss that were delivered from July 2012 to December 2012.
Yes, they predictably screwed the pooch with the updated predictions (5K/week by end of 2017), but in the big picture, all is still well. One of the markers I use is the competition. While true that other manufacturers will finally get into the game late 2018 and beyond, it is also true that NOBODY has the infrastructure that Tesla has. Ergo, all of the upcoming spiffy new offerings from VW and others will remain in-town cars. Fine. Let them cannibalize each other's sales.
Even the upcoming Leaf and current Bolt are still in-town cars until there are more (in the case of the Bolt) CCS chargers. The Leaf is ahead of the pack (the second-tier pack to be sure) due to their free 2-year charging plan. But still - for as much credit as I've given AeroVironment for their excellent $20/month unlimited full-strength and fully-functional Chademo network (see coastal Oregon, for example), those installations are still onesies (1 Chademo, 1 L2) and that's a recipe for frustration in the short term.
Back to Tesla. The full (US) tax credit is preserved for that much longer (perhaps for the rest of 2018 now), and there will be that many more CPO/private party used Model Ss to consider as alternatives to the Model 3 as well. Put another way, people who want a new Tesla can still get one, the waiting list for new Model 3s will still be ridiculously deep, and people who don't mind a used Tesla will have more choices until the Model 3 ramp catches up with the crazy good global demand.
Lastly, there appears, from after hours trading at least, that there may be some nice juicy entry points at which to add more TSLA shares (figure there will be at least one obligatory downgrade coming).
I empathize with those waiting for a new Model 3. The wait for my first Model S was as excruciating as it was relatively brief (about 2 months). But with every week, improvements will be made to the manufacturing process (after all, they still will produce batteries by hand to fulfill demo car needs). Of all of the delays so far, I daresay this is perhaps the least worst - maybe because we knew it was coming. Whoever it was that posted that exposé post about how things really are/were at the Gigafactory did us a service.
In brief, and with specific regard to the Model 3 effort, I'm more optimistic than bummed.
After all, this is a far better story than the AP2 clusterfook, the now infamous December 2016 video, ,the supercharging bait and switch, and the 90kW/100kW battery headgames from this past Spring. Especially since those happened more or less at the same time.
After all a second time, how else would we have seen a billionaire toasting marshmallows over a campfire ON TOP OF THE GIGAFACTORY? While enjoying a proper glass of whiskey, no less.
