Zul'Gurub is gone as a raid instance come Cataclysm.
I'm sad to see it go. I remember full clearing it back in my Vanilla days. There's no insight into what's going to happen to the achievements yet. Are they going to become Feats. of Strength? What will happen to the mounts? We hope to get more info as Cataclysm grows near.
