Why does this even matter? If they released the F-35 today, then you might have an argument. But the release is at least a year off, probably longer. Which means that by the time it is released we'll hopefully have EDGE with several new theaters. As to needing to develop more classified aircraft, why? When the F-35 enters service for real a good number of the aircraft currently in the sim or in development will still be in service. So missions in the new theaters, depending on where it is, could be quite realistic. But then again why does it have to be realistic? ;)
