Might be too late, but just a suggestion:
Change the ARMA 3 engine to CryEngine 3. If not, ARMA 4 should be CryEngine.
Everybody is judgemental toward ARMA and any new ARMA because of the graphics of ARMA 2 (YEARS behind in graphics technology). They then think that any other ARMA game is as crappy graphics as ARMA 2.
ARMA 3's graphics are pretty good, but my god, if you guys used CryEngine, everybody would buy the game.
Win:Consumers have playable graphics
Win:Developers and Bohemia Interactive sell more copies of the game, become more reputable, sell even more copies of the game
