We're on probation, with RRC visiting in April 2008. Our last internal review was a few weeks ago and was much, much more positive than the previous review. The new chairman and new program director, among others, have made great efforts in fixing the deficits and improving the program. I've seen a lot of positive academic changes since starting here and am very optimistic about the future of the program (but i might be biased - i liked it enough to rank it very highly even before the new chairman and PD - call it a gut feeling). You'll be clinically SOLID after 4 years here.
Regarding faculty - we have gained some wonderful new attendings, both from outside and from last year's graduating seniors, and have lost a few as well. From what I understand some of those who left were just not happy (or rather their spouses/families) were not happy with Morgantown - it's a smallish collegetown and if that is not your style it can seem slow at times. If you are outdoors-oriented it's a great part of the country to spend a few years. I'd definitely check the program out if you are thinking about interviewing. The worst case scenario is you don't like it and don't rank it.
PM me if you have specific ?'s
