Good, It looks like economies of scale are starting to work in favor of Tesla; which I find to be unsurprising. Having this car out will shut up a lot of critics as this has been their favorite thing to whine about for the last years. Also it will make them even less likely to suffer an imminent bankruptcy. Another topic that seems to come up regularly, usually just before Tesla manages to move the bar yet again in some meaningful way. Finally, with this box ticked, it frees them up to start planning the model Y, their truck and whatever else they have been talking about for a while.
I would not be surprised to see them announce more price drops in the next years. They are not done making batteries better and cheaper and they seem to be very creative in figuring out ways to reduce cost in their production processes. I think it is that ability that is going to be key to their future because yes they have competition but the competition seems to have all the problems that Tesla already solved. They are ahead of the pack in terms of production capacity, processes, and battery efficiency with a product that so far seems to be selling such that they can do without the traditional overhead of having to have an industry of middlemen, sales, marketing, licensed dealers, etc. That's very disruptive to an industry trying to emulate what Tesla is doing while preserving all of that.
