Right. Since that was a year and a half ago and since his 4 year estimate was based on the end results of the trail, I figured that late 2015 / early 2016 is the most appropriate time to start the math. SO..........hopefully that means that the expedited FDA reviews/approvals will only shrink that time period and 2020 is the worst case scenario. Regardless, B and P will have already made massive advances and at least on will likely be on the market well before that.
