I think the key here is that something substantial has to change from one year to the next. If all you plan to do is polish up a previously sent application, then you should not expect a different outcome. With that said, another year of course work combined with a higher GRE score, a published paper, and a more polished SOP can make a difference. Anyway, just my two cents.
I have two friends that applied to Kentucky and have not heard anything yet. One is a pretty strong candidate that I expect will get accepted there. If I hear any news, I will let you know.
