To clarify (because you’ve made a similar comment in the CGK thread), this is category for suggestions, meaning what players would like to see in the game. Not everything (by far) posted here will get added to the game, it’s just an indication for the developers of what the community is interested in seeing. Just because there’s a post here for an aircraft/an aiport/a livery it doesn’t mean it’s actually in development.
You can find information about what’s coming in World of Airports > Development or in the news annoucement thread:
