Which is a little bit misleading, as the Model S starts at $70,000, but the cheapest Model S that's "equivalent" to a Model X (third-row seats, 90kWh battery, etc.) is over $90,000. So that phrasing might lead one to think that the Model X starts at $75,000, while it's probably $95,000 or more depending on just which features they consider to be equivalent.

There will be a Model X 75D or 80D at some point

True, I didn't think about that. They haven't announced any, but that doesn't mean they won't.

It's on Elons Twitter account (future expected X battery capacities).
