You've named Lock-On/Black Shark/DCS....largely all from the same producer. Rise of Flight...then games that have been out of 5 years or way more. Like I said, where is the new stuff? By all means, point it out to me.
There's been a couple more, so it's not that bad:
- Take On Helicopters is a new flightsim from the makers of ARMA (has combat helos in it, kinda).
http://takeonthegame.com/- IL2 Cliffs of Dover was a new release back in April, even if it wasn't as good as it's long gestation period would suggest.
http://store.steampowered.com/app/63950- Microsoft is re-writing and updating FSX to their new 'Microsoft Flight' franchise.
http://www.microsoft.com/games/flight/- X-Plane 10 is quite a big update.
http://www.x-plane.com/desktop/- Falcon BMS is almost like a completely new game.
http://www.simhq.com/_air14/air_507a.html- Gaijin should release next year their air combat MMO World of Planes.
