Not too likely. The first year production rate seems to only supply the reservations and committed fleet sales for that year. Most of us have encountered a higher rate of those who want it on a purely economic basis who would not put money down, but would buy it now if they could take delivery inside of 60days or so. There could be as high as 10 of those for each reservation holder....if it isn't a go in 2016 I think so many people will bail on them that the entire project will fail......
So it's possible that even if all reservists bailed out, everything projected would still be sold. And since they'll advance delivery to those who do take their reserved Elio's, the left-overs will show up near the end of the year, giving EM plenty of time to adjust their marketing plans.
The fact of 40k+ reservations pretty well guarantees buyers are available at that rate.
