Since Asobo have released the default F/A-18E model. Maybe VRS and other 3rd party developer out there will give this a thought as the flight physics is already there and this developer can make them better and compete with one another who can make em as real as one can get.
3rd developer like Just Flight, DC Designs or Milviz is the choice in my mind to make this beautiful machine.
As for weapons we do not need them to work like in DCS. Merely just a cosmetic would be nice, however a working external fuel is a must.
The ability to fly this beautiful machines around the globe or the Star Wars canyon instead just a small map (like DCS) kinda make one dreams come true.
