A few interesting things that weren't said: 1. Elon said that supercharging is standard. But he never said that it would be free. As-in, the door is open for some sort of pay-per-use system. This makes sense, because when the cars get less expensive, I can see it attracting more people who will look at the SCs as a way to save money on power at home, rather than as a means for doing long distance travel. 2. Same with AP. He said, specifically, that the AP hardware is standard. He did not say that there would not be an optional cost to turn it on. I suspect this is a bit of "keeping the options open".
