Well thanks to Brewster, I DID end up listening to this Q&A - as always very interesting... I noted the following:
Elon Musk said the Model X configurator will be on the website by the end of the month, a few weeks before production is due to commence, deliveries to occur end of September.
They are still interviewing candidates for Deepak's replacement (the CFO) and he will hang around to ensure a smooth transition, but I fear that his replacement has really huge shoes to fill which will negatively impact Tesla.
The trouble with the Model X seems to be the second row seats - and at another point, Elon described it as the hardest car in the world to make.
The Fremont factory was closed for a week for improvements. Both the Model S and Model X will be made from the same main assembly line.
The improved paint shop (I think is not yet operational) designed to do 10,000 cars a week (far out) has been upgraded with model 3 in mind - though no other factory improvements have been made with model 3 in mind.
