I think anyone that ordered after the $2000 Model S60 price increase will get a 90 kWh battery minimum. My reasoning behind that: 1. A $2000 price increase at a Tesla cost of $150 per kWh is 13.3 kWh increase over the 75 kWh battery for a total of 88.3 kWh. The profit from the base model would be unchanged and this would mean the $2000 price increase is more than drumming up business. 2. Tesla likes to simplifying production and if it only makes battery modules used in the 100 kWh then we get an 87.5 kWh battery (100 kWh / 16 modules * 14 modules). Also everyone knows Tesla likes to round up so 90 kWh.
