Do you have any idea when that will land in the open? Say, before 2018? Or maybe a little sooner?

This is even more the case with software. If this cost 20 or 20 million man hours is irrelevant in the long run because eventually it will be used enough to offset costs if it is as good as every one says. Of course short term cost hurt now, but sounds like you still had computers do much of the heavy lifting.
