Then bug SimFlyers or something, They have to finish their simulation engine, finish JFK, then do DFW, then make an aircraft, and THEN finally make some secret. I think their agenda is full for right now.
I've actually not requested FSDT or you to create MIA. I was just not agreeing with the previous comments that Flytampa's MIA is still good, it was good a decade ago when it came out but time passes and things changes. (literally) I rather see more european airports or asian, american airports are simply too boring.
