TA has 3-4 attractions coming with it (the Encanto attraction, the Indiana Jones attraction, the carousel, and the rumored Indiana Jones themed play area), the Monsters Inc and Cars Mini-Land both have 1 major attraction and 1 smaller attraction, and Villains I think has 2 major attractions coming with it with some smaller attractions probably coming with that land as well. So two rides per new land being the norm doesn't seem to really apply for any of the new lands coming to WDW in the next 5 years
