Oh, one point beyond 2018. If at the end of 2020, they have $1b revenue and 80% profit margins the the price calculations are everyone gets insanely rich. So before I start mentally spending all my SAS cash, I'll wait until the end of 2018 to see how it goes. If the deliver value like they expect and the market responds like I expect, then I'll have a better grip on what the 2020 price may be.
