My crystal ball says (and we all know how accurate those are):
Failure rate could exceed 20%.
Reading between the lines on the press release with the information available publically (i.e. an "increasingfailure rate after implantation) I suspect that there will be non-hermetic implants. Not good. But take it for what its worth. It is a crystal ball predicting this.
