One year and a half and counting ... really ?
I don't know what you are trying to say here.
We released other sceneries in between ( KCLT, the CH Mesh, LFEQ and LFNC ) and we are obviously working full time on GSX. It's not we ever made any promises, discussed any release dates, or made a Kickstarter and asked for money in advance for KIAH. It will come when it will come.
