Ok.. I got the article
The game is supposed to provide pilot with more than 100 000 sq kilometers of historically correct terrain for the 1917-1918(some like it easy apparently ). Il-2 engine is heavily modified - the graphics part is going to be amazing(trees are finally trees - not layers of green paint).
There's gonna be 13 flyable planes(German, France, RAF, USA) and about 30 will be AI-only. Throw in nearly 60 types of ground units as well. To get the feel of level of plane detail have a look at the screens at their website.
TrackIR + Vector are going to be useful(if not necessary) and fully supported.
Multiplayer seems to be one of the developers' priorities.. it's possible that KoS will have air war mode like Warbirds or GT's Air Domination War for Il-2.
