I don't think people are necessarily calling this the Forbidden Forest, but it seems more like it's seeming to be partly how Muggles see Hogwarts, as a series of ruins.
The Chamber of Secrets, Forbidden Forest & Great Hall in a sense, have been already done in Forbidden Journey; and that Pivot Dr. really doesn't have anything to offer for any form of experiences.
Odds are, for the core Potter series..this and Ministry will be what's left for USF and IOA, and then we may see an influence of the Fantastic Beasts franchise down south.
That said, I am interested to see what the new structures add; as they clearly aren't from previous stories in the Potter franchise on a large scale. Even the Barn building isn't even looking like Hagrid's Hut.
