Elon king of overpromissing and underdelivering. The P85D has been delivering. Autopilot funcionality isn't fully available but has been coming one step at a time.
About range anxiety, perhaps enabling navigation for all cars, warning people if their current destination leaves less than X miles of reserve range, pulsing the motor for lower energy consumption (by going to the set speed and letting the car coast to 5 mph less, cycling this process continuously), and enabling the motor sleep in the D.
Finally, a retrospective of already delivered supercharger stations, and a commitment to having SCs every 80 miles on every major interstate, a supercharger for every million people in metro areas.
"End to range anxiety" doesn't mean immediate, it could be a year long process.
The real problem Elon brought onto himself is he was so brutally honest and delivered so much we expect him to come through perfecting moving forward, which becomes harder and harder as people become more and more demanding of Tesla.
Finally, perhaps a solar panel for Teslas. Even a modest 5% gain in range daytime, and the ability to fully recharge in 3 summer days with full daylight is nothing to sneeze at.
I read his statement that some of what he'll announce is a software upgrade, but perhaps not everything.
