Sealed Box after Cata

Q u o t e:
Is it possible to find out if the Sealed Box that drops off from LK with a Shadowmourne for the first time will still drop off the LK when Cata hits?

I have actually answered this one before, well as best as I can. I'll paraphrase.

As I said before those of us who work in In-game Support wouldn't be able to answer that. One of our Developers would have more insight 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, if anything the encounter may be adjusted at some point but who knows what the future will bring.
