To me, from the way it was written, seemed like an advertisement to get suckers to come to DHS this winter. If they have a plan to move it or bring it back, they certainly aren't going to announce it now when they could say it's "going away", everyone cries and comes to see it, then Disney says, "just kidding" about 5 years later and announces they are bringing it back to massive fanfare.From the way this is written, I would guess that best case it is gone until HS becomes a real park again, worst case (likely) gone permanently. If they were moving it they would have said so and made a big to-do out of it.
Not saying that's happening or it will ever come back, but I wouldn't read to much into the wording other than DHS needs people for the holidays.
