As Zheo said, precedent from BC would suggest they'll be removed. Which is sort of funny to me, given that the pair of titles were IMO much more difficult to earn than Kingslayer on normal *right now* with a 30% buff. Even after 3.0 dropped and we got the new talents.

It's especially a shame given that Blizzard picked now to spring the lockout changes on us, without changing the loot tables, as well as the new mount changes. I know a number of people who have just joined guilds after being stuck in Pugsville for ages that probably won't ever get Kingslayer if this turns out to be the case. Before the mount changes became clear, it was a hard enough decision to have to make, gear vs. drakes. Now? I don't even know, man. My own guild is likely to still focus on our 10 man drakes for those that don't have them, because they're cool mounts, and we're already so close (my 10 man group just has heroic Sindy and a couple others) to go. But a lot of guilds are going to have even tougher decisions to make and I don't envy them.
