the rumours suggest King Kong now and I thought that was instead of the once planned Jurassic park attractions, however I would have thought a new jP ride would have been the better option with Jurassic World released in 2015
Disney won't be too worried with close to 50m guests per year across the 4 parks, and will remain Orlando's biggest draw. Universal have said what they want to do is encourage guests who are in Orlando for Disney to spend a couple of days at their resort rather than spending the full hol at Disney world. Disney have introduced dinning plans and now magic+ bands to encourage resort guests to remain on property.
Disney wasn't hurt with the original Harry potter area, and back in the late 90's Disney became very worried about the impact IOA would have when it opened in 1999 and planned a new major ride for each of their parks (fire mountain for magic kingdom, beastly kingdom for animal kingdom, villains ride at Hollywood studios and unknown ride for Epcot) however when IOA didn't perform as expected and had no impact on Disney world attendance Disney canceled all those projects. Shame as would be great if universal did start to have an impact on Disney so we get more attractions added at Disney world.
