A couple of observations from the VIN:
1) It seems like Tesla intends to sell a dual motor Model 3 in 2017, since it has provided an option in the VIN for that.
2) It seems like Tesla does NOT intend to sell a "Performance" model 3 in 2017, since it has not provided an option in the VIN for that.*
*Note that Tesla appears to be using numbers for the drivetrain designations in the Models S and X, and letters for the Model 3. I don't know why that is, except that I guess that the motors are likely different between S and 3.
