There are 3 information sources - your DS, the website and e-mails. And they may not always be in sync. Trust the source that updates new status first.
For delivery - the most important notification will be when you're contacted to schedule your delivery appointment.
Just heard from our DS. Looks like tesla has changed the process for deliveries (at least for Texas) and now require us to pay for the car before they even ship it. This is what they did with our first S P85 in January 2013 - which they didn't do for our S 100D last year.
