First reason might be that Flight Simulator X has finally not improved really the former one except in being incredibly far more greedy for memory

Even worst news, with the current economic crisis Microsoft had announced in last January that ACES Studios, the studio behind Flight Simulator, would see part of his employees fired.
At the same time rumours were that Flight Simulator 11 was to be released on late 2010 or early 2011 (as seen on Phil Taylor's blog).
I have many expectation for this new Flight Simulator to come. There is still so much to do on Flight Simulator saga !! Whatever scenes you have added to your favourite simulator, just watch the following video and cry .... When Flight Simulator will be as beautiful ??
