You might have read this on other blogs already. For example Francois and Lefteris wrote about this already, but I feel it is too important to not repeat it here as well.

There is a “new” flight simulator that is being marketed currently. The ads promise that it is the best out there and even beats FSX. Did we all miss some new development or is there another side of the story? It turns out that this “new” simulator is actually a commercial version of FlightGear. So the marketing is a bit misleading, to say the least. Be aware of that.
