Interesting but good news MarkOz. My concern these days is that MS with their new Flight Sim (and it looks very good) is going to be very different such that scenery addons, weather addons will be redundant and my assessmsent so far is that as they are now using a new modelling engine it will be very hard for most sim model developers to rebuild FSX stuff to work in the new sim. P3D is a good bet.
