It's always been said that the Wizarding World of Harry Potter's lands, are considered as "Timeless" (outside of the attractions, of-course); and with Fantastic Beast's being set many years before the journey that Potter takes place, it could make theoretical sense that once FB enters the parks fully, there would be a brand name change, more to "The Wizarding World", as it will focus on two radical time-periods.
The period of Potter's journey in Great Britian of the 1990's, and the period of Newt's Journey throughout the world in the 20s (and probably 30's). I wouldn't be surprised that Tina becomes a more, integrated element in Newt's journey; as much as how Harry had Ron and Hermonie alongside him.
I am curious to see how things differ, and stay the same for the films. As, it will bring many interesting, and somewhat possibly intriguing concepts to go in. With Paris as the new film series's next stop, and Dumbledore and Grindelwald being in it; it will be fascinating to see what occurs next, for better or worse.
That said, Forbidden Forest makes sense on a geographical perspective, and that it allows the team to fully immerse individuals in what is, an iconic location for the film series. What there could be, is more fascinating.
