I just got off the phone with Tesla sales in Paramus, NJ and got some more information regarding the new Model S&X with AP 2.0 Hardware. I was discussing trading in my Model S (pre refresh March 2016) for a 90D Model X with the new hardware. After hearing everything about the new hardware, I will definitely NOT upgrade until at least the new versions are on par with what I have now. This reasons are because: If you take delivery of the car with the new hardware, you are actually getting LESS features than what cars with AP 1.0 hardware have. 1. Automatic Emergency Braking 2. Collision Warning 3. Lane Holding 4. TACC Out of these four, to me, TACC and Collision Warning has the most impact. I use TACC on a daily basis (every single time I drive my MS) and Collision Warning, which has proven to be very useful. With Tesla's track record of over-the-air updates, I doubt the software updates will be on time. This could potentially mean no TACC until early 2017. Now, the reason why I believe what the sales representative said: Tesla introduced new hardware to the Model S&X and the company needs to collect new data from this hardware (hence, Elon constantly using the word "shadow") The reason why the 4 features I mentioned are unavailable is simply because they need more data to make sure the initial release is on par with AutoPilot 1.0 hardware cars. Just a note, I am HUGE Tesla supporter (Model 3 reservation holder) and love driving my Model S. This is just what I think about the product announcement last night.
