If I sit down and dream for a moment I imagine this:
DCS offering the following aircraft in some years to come:
US:
A-10C, F-18C, F-16C, F-15E, AH-64D, T-38C
F-4 Phantom
RU:
SU-25T, SU-33, Mig-29, Ka-50
Mig-21
Classics:
P-51D, Me-109, Fw-190, Spitfire, Hurricane
Maps: Georgia, Nevada, English Channel, Korea, Iran, Atlantic ocean (for blue water carrier ops)
Plus SFM aircraft from Flaming Cliffs...
I imagine this could take decades but possibly less with third party development partners.
