It reads to me like just idle speculation based on the fact Tesla has previously stated they'd break ground in more than one place. To actually fully build out more Gigafactories, they'd have to line up a bunch of partners and suppliers and so forth. Tesla got enough cash to fund one GF initially and while they've talked about multiple ground breaking to mitigate risks of delay, I really doubt Tesla can afford to fully build out multiple Gigfactories simultaneously at this particular point in time.
Now, fast forward 18 months and Tesla is shipping at a 100,000+ run rate and the X is winning every award imaginable, and we'll have a different story. Tesla will have some major proof that multiple GFs really need to be built.
Thank you Ckessel for voice of reason! I did have similar thoughts as well, and yet, when I think about JB Straubel, talking about stationary storage, saying that it comes faster than anybody thinks, and saying that we need to think bigger... Or Elon saying that they are not showing all their cards, and R&D expenses do not look as bad as it apears because there are things you do not know about...
Do not take me wrong, I do not think that they will jump to building everything at once, but they might lay out a bigger coherent picture for the first time publically, and tomorrow's event would be a good time to do it. If they talk specifics about GF #2 and #3, that would be a huge leap from the hints they were giving over some time, and would be huge boost to TSLA, which, incidentally, they will need if there are thoughts about raising more money...
