The modern business jet Challenger 605 of Bombardier in current development by Eaglesoft Development Group will be a product for FSX and P3D v3, in a first time. They named that product series Extreme Generation Three, and there will be the Cessna Citation X too.
In a second time, those aircraft should be developed for P3D 4 too.
Wow! Can’t wait for it when it’ll come out in approx 7 years
