I just want to make sure I have this 100% right. As I understand it from the Avsim review, there is not equivalent of the gamepack that came with MS2K 2K2 9 and 10. I take that to mean that developers cannot create add-ons such as aircraft, airports, weather management, ATC, etc..? Is this correct? Am I also correct in concluding that this means VATSIM will not be able to use Flight?These are straight questions, not commentary. Seriously asking.

Not at this time no. Whether there ever will be one is an open question.

MS has gone with closed development. We won't be seeing any SDK's.

OK, thanks for the clarification. I am sincerely thankful to you guys for taking the time to get all the details for us.
