So, I guess it doesn't work...

Question: They have the SU-25 and the A-10A as DCS modules. Are they planning on making the rest of the FC3 stable into DCS modules?

I think they are yes. It's purely license reasons, in that FC3 is actually on Steam as a module, but you have to access it using a Russian account (Ubisoft didn't have the rights for the CIS).

The Steam / non-Steam versions are pretty much identical apart from the Module Updater, so some even copy over their FC3 module in without problems - but of course it doesn't update via Steam, so you have the hassle of keeping two versions around.

The Next Eagle Dynamics DCS Modules

Later this year, we will offer:
A-10A: DCS Flaming Cliffs
Su-25: DCS Flaming Cliffs
F-15C: DCS Flaming Cliffs
Su-27: DCS Flaming Cliffs

These modules will feature:
1- Detailed 3D model (high polygon / high res textures)
2- 6 DOF cockpit
3- Advanced Flight Model (AFM)
4- Same level of cockpit system detail as the Lock On: Flaming Cliffs aircraft

We plan to release each at $19.99 USD.

We are releasing these modules for the following reasons:
1- It allows users access to these aircraft that do not own, or want to own, Lock On.
2- It allows users to buy just the aircraft they are interested in, without having to purchase the full Flaming Cliffs product.
3- It allows us to make these aircraft available to a much larger audience on Steam, Origin, GameFly and other digital retailers.

These updated FC3 aircraft will be made available for FREE to Flaming Cliffs 3 customers.

Other FC3 aircraft will be improved as well (like the Su-27, Su-25, F-15C and A-10A). When they are further along, we will discuss them.

We will develop a balance of lighter "DCS Flaming Cliffs" modules with more detailed/realistic "DCS" modules. The "DCS Flaming Cliffs" modules allow us to develop the more detailed "DCS" titles in a more iterative way. As such, we will continue to develop detailed simulation like A-10C. The next such "DCS" title will be F/A-18C.
