The real reason , as I said , is ED knows the next DCS jet is the most waited and anticipated module they are producing,but before that ,they have many other product to sell. They hope to keep us concentrating on their product.
Both "Everything is subject to change ,and they haven't reached an agreement with the military" are not the point , because ED dare to say the next module is a modern fast popular us combat jet and they have been developing it for most a year. How could they say that before they themselves don't know what to develop.
ED is a great company and also a Smart businessman.
