Almost four years ago, QualityWings and Enigma Simulations merged. This last team had the 737 Classic project already running for a while and the final product should have been rolled out under the brand of QualityWings.
According to the story of the leading manager, Enigma members remained on their own side working on the 737 and not on the 787. With the time going, they left QualityWings and their work on the good old Boeing one after the other. QualityWings clarify that now the project has to be considered as cancelled.
About the 787 for FSX, the HotFix 2 is about to be released. Then will come the Service Pack. Only after this, they will start looking at P3D v4.
