My bet is that the Model III with come as standard with, heated seats, supercharger (built in), Auto-pilot (built in), AC and infotainment system ala Tesla. Navigation is likely to be optional (even tough the hardware is there) and the base car will come with alloy wheels. Personally since im buying on a budget, if i can activate supercharging and autopilot at a later time i'll go that direction. The Model III will have a 60KWh battery, for the simple reason that the Bolt has a 60Kwh battery. As for telecommunications, i hope they use the same system they have in the current Model S. A simple LTE gsm modem, that you can swap out the sim card. With said system the car can have it's own telephone number, allowing for text, calls and data communication. My current tablet plan from T-mobile cost me 10 and has 3 gigs + unlimited music and video streaming.
