Sad to hear that there are no news today, I was really excited (well, I am still excited to hear something about the new sim, even if not today, but in the future).
But in my opinion: take your time and create a working sim, it is more important to me, that I do not have to make it run without bugs or optimize it, because this is the annoying thing and costs a lot of time, which I even could use for flying.
