I don't see any pull-ahead of the milestones. if you compare it to the Feb 2014 Prospectus, it is basically the SAME time line, with one exception - Tissue Validation Study completion has slipped from Q4, 2014 to 1H 2015. What they did was decrease milestone granularity - switching from quarters to half years. Basically, they have given themselves wiggle room in attaining the milestones. A milestone can move from 1Q 2015 to the 2Q and still be within the 1H 2015.
