If I understood it properly, there will be bigger battery pack for Model S maybe already next year, AWD for Model S will probably not come before Model X, AWD does not have an impact on range, gigafactory will be built and they want to achieve price reduction in battery pack at least 30% hopefully 40%.
Autopilot might be introduced before 3rd generation and they believe that they will be first ones to do so. If they introduce autopilot for reasonable price (like 2-5.000 USD depending on what it can do) as first in the market than for me it will be a proof that Tesla is really much more capable than any other car manufacturer. All big producers are working on it for years. If Tesla will do it as first than it will beat them at their own game, which would an incredible achivement.
There were a few more important things on top of that:
-JB said that Tesla breaks even for car manufacturing in under 10,000 miles. Tesla will publish whitepaper of the data.
-Seats will get an upgrade around this week. (something to do with springs and comfort of sitting)
-New premium seats next year as an option
-CHaDeMO adapter in April
-Proximity sensor on top of Model X falcon wings would only open if there is enough room for a person to go through
-No AWD Model S for a couple of month, will come out close to X
