Since it does seem like Ohio will go Republican in a narrow Democratic victory, Florida will become the "ultimate bellwether" once that happens. I do think that Wisconsin, Michigan, and Pennsylvania will (at least in the short term) flip back to the Democrats if they win in a close race, but since they went for Kerry in 2004, Florida will be the longest standing bellwether. Also, poor Nevada. It was going to be the next bellwether, but it proved that it's just too blue for that, not that I have a problem with that.
