Yah, my point about the X was to hint that projections are not final by definition.Interesting though that it wasn't accurate with the X.
As far as the particular issue (dropping 40 kWh), I think they learned some things (and are still paying in PR) about 40 kWh with S and made (IMO) a less-painful-longterm choice for X based on that. Of note is that the "similar to the Model S" part is essentially retained (same 60kWh and 85kWh battery options, with a reportedly slight decay in expected range),
