Some of those are proof of concepts and/or facades for possible future content. They are not all guaranteed to go into production. Dishong is still currently the tallest skyscraper in A22 / 1.0.
We are still focused on downtown remnant POIs currently, but it is still possible for extra unplanned content to squeeze in if we have time so there is still hope.
Out of curiosity, what new POI would people like to see in A22 / 1.0 if you could only pick one? Sorry, no airports or yachts...😁
