I for one upgraded my system 6 months ago to a top notch one that runs FS9 with blasting framerates.
I have FSX laying around here somewhere but after the first install I removed it again.
My FS9 has lot's of great addon planes and scenery so setting up for FSX again would take way to much time and effort.
And now with the way things are going at Microsoft I'll stick to FS9 and that's it. I even tend to think that there will be lot's of other FS enthousiasts around the world that will do the same.
So yes, I would love for CS to keep FS9 support up.... Just look at other great addon plane and scenery designers, they do !?!
