Saw this on SimHQ:
"Dear Pilots,
We are proud to announce that the 1CGS development team has recently begun work on Ilya Muromets, a new standalone flight-sim in cooperation with the Russian Military Historical Society. It will cover a little explored part of the WWI air war – the Eastern Front. Ilya Muromets will feature the gigantic and legendary four-engine bomber of the same name which saw action on the Eastern Front in service of the Imperial Russian Air Force. This plane can be considered the genesis of the multi-engine long-range strategic bombers of later conflicts.
More info can be found on the Ilya Muromets website and in the discussion forum.

About the Game - About the project - ILya Muromets Forum
Ilya Muromets will feature several additional fighter planes and attack planes from Russia, Germany and Austro-Hungary. A map covering a portion of the Eastern Front near the Ukrainian frontier will be included. This was an active theatre for the Ilya Muromets during the war where several famous missions took place. Speaking of missions, Ilya Morumets will include a set of challenging single-player mission scenarios along with a quick mission builder and multiplayer capability. Ilya Muromets will be built on the same game engine that powers Rise of Flight: The First Great Air, but will be sold and marketed as an independent product in cooperation with the Russian Military Historical Society who has provided funding to allow the Ilya Muromets to once again take to the skies. Existing ROF customers can experience the Eastern Front by purchasing Ilya Morumets.
Expected release will be Q4' 2014. Early Access targeted for August 1st.
Sincerely,
The 1CGS Team"
