I picked up this quest on my 70 rogue on Ghostlands about a week before the patch hit, aiming to finally get attuned for Onyxia (I took too long to get to 60; by the time I reached the required level, BC had been out for a month). Got patch 3.0.2 dl'ed and installed and found that the letter to Fordragon had turned into a letter to the King (who is back now). I turned it in no problem, but after completing this quest, the chain just stops. Now it's only the day after the patch came out, so a lot of things are still shaky, but as it stands, neither Fordragon or Lady Prestor are in the throne room anymore. I'm assuming they'll fix this in time, but it's probably a relatively low priority. With the advent of the achievement system, however, at least people have incentive to do Ony again, so we know this won't stay broken for TOO long. I'd say give it a month.

EDIT: Since Onyxia no longer requires attunement, the quest chain is moot.
