The next A-10 sim will be part of the Digital Combat Simulations series from Eagle Dynamics. Have a look at the first look of the series which focuses on the ‘Black Shark’ KA-50 Russian attack chopper. Read it here at SimHQ.
The Hog is next in the series. When will it appear? Late 2008 is possible. See the DCS site here for all the info. Still it looks potentially great.
