Has anyone thought about the timeline for the Model 3? I haven't found much in the way of discussion beyond "release in 2017". I'm sure this is easy for people who followed the Model S/X development closer then me. I'm wondering if we can back into guesstimates on upcoming dates for the Model 3, based on a target release of 2017. For example, T-x months for exhibit at a major car show, T-y for deposits, T-z for photos of a clay model, solid specs, etc. I'm wondering when I can see solid specs (performance, range, etc), official pictures of the clay model, and when I can put down my deposit. And if they do a Signature series, what does that really mean? What, exactly, did you get for a Signature reservation on a Model S? A bigger deposit, a priority slot, and choice of another color? Anything else? Were the Sig's more expensive than non-Sig's?
