True, but I believe that they also have a policy of 'specific trumps general'. If that's the case, then Pistoliers aren't screwed.
Again, when the *7th* edition army book comes out for empire, then pistoliers will have what they have. But until then, new trumps old.
Again, many *3rd* edition books had specifc rules that got overrode when 4th hit. And then the newer codex came along and overrode 4th.
It SHOULD be the same way with fantasy. All specific rules are overrode until their newest book comes along....I hate to say. But thats how its been.
