That's what I was told last year. Then things changed and now JP is getting an upgrade/overhaul. And I would bet money it will be a JW overlay.
So I'm pretty sure JP will be slathered in JW colors and signage, and we get a new attraction.
With no information on the Orlando site, I am betting that Jurassic Park will get a Springfield level transformation, to match Jurassic World in it's design and style. It makes a lot of sense, and would help with the flow of the new attraction coming.
