IE 8 gets, for the most part, to end of life next January. So it should go back into shrink mode as those IT departments get with the times.
I am working on a project to be delivered to CA Dept of Public Health around January. We were told to target IE 8 as our minimum browser (as well as FF/Chrome/Safari). Seems a waste, given this news. Time to push for IE 9 or better.
