The official IL-2 Sturmovik website features exciting news for the flight-simmers among us (which would be Brian Rubin and me): first of all, an expansion for IL-2: Forgotten Battles is in the development. Unfortunately there's no information yet on what exactly we're going to get to see and play in the add-on.
The second announcement is more significant though. If you were hoping for the Maddox team to cover a Western scenario, you'll be pleased to hear that the next big project is going to be based on the Battle of Britain. You'll just have to wait about two years for the game to ship as it's currently set for a release in 2005.
