I think MS didn't actually cancel FS when they shut down Aces as much as they figured they were spending way to much money going down that road. Now that the market is returning they believe they have a much more cost effective way to proceed with FS.

I watched the teaser ... and I'm still waiting for a flight sim that includes ground loops - voiceover talking about the Stearman takeoff, "See how easy that was? " after virtually no rudder action on takeoff roll - Even a locking tailwheel won't stop a groundloop - lol.
