I think they've "reformed" since endgame BC, actually. They're drawing their power from the re-energized Sunwell now. But they're still effeminate, excessively androgynous wimps with the most boring, generic faction leader in existence.
Maybe they'd bring the gnomes along, so that UC would be a radioactive crater instead of a normal crater. On the other hand, this might end poorly - similar to how the only thing worse than a zombie is a flaming zombie, a radiation-drenched Forsaken has to be worse than a normal Forsaken.
