I got the impression that eligibility had to do with whether a vehicle qualified as a Zero Emissions Vehicle under the regulations and guidelines of the California Air Resources Board (CARB). But even if it is only the cars that are built to US specifications, meant for sale within US boarders, Tesla Motors is likely to be very close to the mark before the release of Model ≡. My estimate is that through 2016, Tesla will have sold 140,000 eligible units. By mid-2017 Tesla is certain to gone over the mark at 200,000 -- whether the Model ≡ had been released yet or not.
