I guess I don't understand why you don't understand. How any of this can be puzzling to you is odd. I only wish I had enough posts to see how ridiculous your vaporware topic reported on by xsimreviews was. It's pretty clear that this project for upgrade has been going on since before X-Plane 10 was even a thought, and it was promised as a free update, as well as labeled 1.5. There is no pre-requisite to follow the "Steven Winslow" way of things, is there? These guys can label it how they wish to! You are clearly making noise about almost nothing. Tom has been pretty open about the planned roadmap in time throughout this thread. Part of that roadmap includes an in-between hybrid of version 1 and a version 2. This equates to 1.5, with a 2.0 (as I understand it) to be practically an entire 3D overhaul. I thank the efforts of Tom, Ben, and Cameron here for all they have done. While some like Steven enjoy to complain, I am entirely grateful for your efforts to bring this bird to 64-bit, label it as 1.5 (who gives a hoot?), and give us a middle marker until you reach the end of the threshold (2.0). Great work!
