To me, this makes sense if it is brought to ARMA 3. For ARMA 2 you can more than likely just drag the revised Chernobyl map from the DayZ standalone to ARMA 2 - May have to bring over some assets, but don't think it'd be too difficult.
TOH is indeed needed to make ARMA 3 THE GAME it needs be. from like a year ago i remember hearing that TOH would be implemented into ARMA3 for the helicopter physics, etc.
