With regards to the "7 lands" comment, I don't think Disney actually has plans for seven specific lands in mind.
I think a lot of people read Iger's words as literal, but in a lot of these panels and shareholder meetings, I actually don't think they are.
Consider all the buzz in 2015, which Iger's words suggested a new name was coming to Disney's Hollywood Studios. That never happened.
Then just last year, Iger "announced" Frozen 3, Toy Story 5, and the Disneyland Avatar experience. None of those things had been publicly shared, and even the company's own producers and screenwriters were surprised.
I think Iger speaks a lot to things that are being discussed internally, but none that are definitive.
