The so called "long awaited aircraft" must be the one we are familiar and complicated; that is we known from current information.
The aircraft complicated and well known could be:
Bomber(F-111, Tornado IDS)
4th Gen. Jet Fighter: F/A-18E, F
I wish we can get Rhino Foxtrot one day in DCS world.
F/A-18F early version with AN/APG-73 seems not unrealistic. The VRS are building F/A-18F for P3Dv4(and for new Microsoft Flight Simulator in the future.)
