What I do wonder is, once they implement the weather system: will we get some sort of weather-prediction system? Visibility can be quite important if you plan an action: covert wouldn't mind going in in a big rain/sandstorm where as a big vehicle action might prefer clear skies.
I'm not saying that it would have to be accurate, heck if the system "gets it wrong" it might even be funny
But some sort of meteo might be nice.
