Sealed Chest in Cataclysm?

Q u o t e:
Will the Sealed Chest (http://thottbot.com/i51315) and the 5 items contained within that drops from Lich King the first time you kill him with shadowmourne be removed when Cataclysm is released?

I'm afraid those of us who work in In-game Support wouldn't be able to answer that, Deatheternal. Perhaps one of our Developers might though if they intended to release information about something you would likely see a post or it would be in patch notes.

It is unlikely that it will be removed, Deatheternal, if anything the encounter may be adjusted at some point but who knows what the future will bring.
