This is pretty simple. To those of you in the beta (or are simply knowledgeable), which reputations are being removed in cataclysm?
I know that the Zandalar Tribe is going away with the removal of Zul'Gurub. I assume that the centaur reputations in Desolace are gone. Same for Ravenholdt.
I haven't been able to find an answer (or at least a firm, recent answer) on reputations like the Hydraxian Waterlords (very possibly removed) or Shen'dralar, Thorium Brotherhood, Cenarion Circle et cetera. I'm nearly positive the Timbermaw Hold and Wintersaber Trainer factions are still going to be around, but hey, I haven't heard a definitive answer either way.
Not worried out on missing out on recipes, though. It looks like scribes are going to get a "craft old world recipe" pattern. However, I do have a pavlovian response to rep grinds, and don't want to permanently miss out on any.
So... what reputation are sticking around, and which are leaving?
