You can look at anything they've done recently and you'll find
@lazyboy97o is absolutely correct.
The most recent original Disney rides built that come to mind are in Shanghai.
1) Soarin: a well proven concept with a new film and preshow
2) Roarin Rapids: a new exterior to a well proven concept with some Everest plot thrown in
Compare that to Frozen, 2 SWE, Avatar, GotG, all the other Shanghai rides, the not so new Fantasyland, Toy Story Land, Cars Land, etc. While Hong Kong should definitely get credit for Mystic Manor and Grizzly Gulch, they are following that up exclusively with IPs. That was also due to the government intervention.
Look at the Disney of the 60s and 70s that brought us classics like PotC, Haunted Mansion, Space Mountain, and Big Thunder or the Disney of the 80s and 90s that brought us EPCOT Center, Disney's Animal Kingdom, and attempted more IP free concepts (WestCot, Disney SEA, America).
Even just comparing the ambition and risk taking of today with their long history is embarrassing. They just won't try new original rides unless it's using a preexisting concept or their government partner is twisting their leg.
When people voice their disapproval with the flood of IP, they have a factual basis. Not even the flood of IP bothers me as much as the lack of care that is usually associated with it. I like Fantasyland, but everything should not be Fantasyland; especially if Disney has already promised to tell a certain story to their guests that can't be reinforced by Frozen or Zootopia.
That makes the whole park somewhat of a pointless incoherent mess.
