While it came as no surprise that someone killed him, what surprised me was that it was Ensidia. I was betting on Vodka (can I get a 'for the Alliance!' from anyone?) and that they managed to do it while many of the EU realms were having stability issues. Of course, it should be noted that Ensidia was the same guild that cleared all Wrath content three days after its release (they hadn't decided on a name yet).
Boubouille over at MMO Champion has a full raid list and info on some of the loot that dropped, including a rather nice cloak and a piece of that legendary healer mace.
