The exchange on the subject of increased GF production between Andrea James, Elon and JB Straubel took place during the Q1 2015 ER Just to make clear, the discussion was more like kicking the idea of the increase of production around, rather than revealing specific plans. My interpretation of JB's response is that GF output could probably be increased by at least by 50% from the 35GWh cells / 50GWh packs to 56.25GWh cells / 70GWh packs. Given that increase was totally attributed to the increase in anticipated BES demand, I think that this means that overall pack production will be split evenly between the TE and TA, i.e. 35GWh each.
As for the batteries for the MS/MX, you have to remember that the original 4 year agreement with Panasonic remains in force, i.e. Tesla still required to buy cells from the Panasonic factories in Japan, which is totally logical, as Panasonic would not agree to invest in the GF1 otherwise.
My understanding as well. Also, the expansion of Gigafactory1 is underway by the addition of additional floors to increase the area by almost 40 %. This figure could increase further as Tesla and Panasonic become more efficient at production output per area of floor space, so 50 percent may well be a reasonable final increase for Gigafactory1. As several have said in the past, the footprint will remain as in the original plan. Tesla's dilemma is the strong demand for both energy storage and Model 3. Elon has said that Model 3 would have priority since battery production is essential to maintain production of Model 3 at Fremont and, potentially, at other Tesla car factories.
