Come on. Counting Villains rides is a cheat. That land has as much chance of happening as if it hasn’t been mentioned.
If everything else gets built it’s a net addition of MAYBE one attraction, depending on the location of Monsters. If you want to give Disney the benefit of the doubt and count only “rides,” it might be an addition of three rides, one of them (the second Cars attraction, which is far from guaranteed) likely a flat.
Before the announcements, reliable insiders were reporting that we were getting ADDITIONAL capacity in the form of major Coco and Moana rides at MK, possible additional capacity from an AK Lion King attraction, and keeping Rivers of America and Muppets. The D23 announcements were really quite awful.
