Go to the EKI website and put your name on the waitlist (aka "Notify me when in stock" email). I can't imagine they don't look at those as a metric when deciding which production models to make next. If there's 500 people on the wait list for model X and 50 on the list for model Y, it only makes sense to build model X next. Typically, demand drives supply. I know it does where I work.
