Not sure how much pull Elon has about this sort of thing, but the headline at least gives some hope that it won't be (more) months on end:
Elon Musk: Tesla is speeding up production and installations of Supercharger V3
There are a number of aspects of Supercharger construction that are out of Tesla's direct control. Permitting and local utility hookup are two that seem to generally be problematic (and weather, in some other parts of the country). Increased Supercharger production, while a good thing overall, won't solve those.
