There's a huge difference between local apps that cost one time 3-10$ and apps that ask for a subscription between 5 to 20$ per month. the first category will remain and might become more popular as quality increases, the second category will be oblitereated as the value isn't there, even if all the buyers are rich. The second group takes up a much larger part of the pie than the first though, so apple's revenue will decrease.
