The Model S Options and specs pages contain a new hidden menu option to the delivery walk through video: http://www.teslamotors.com/models/walkthrough
I guess they'll unhide it soon...
It's unhidden, but looks the same as the official Vimeo walk-through they unveiled about 2 months ago: http://vimeo.com/56110773 PW: t35la4ALL
When I say "hidden" I mean the Model S page(s) are supposed to have a new 'walkthrough video' menu option. It is there on some pages, but marked with the 'hidden' attribute.
