Barbarian unit stats in Gods and Kings

Is there a reason why the Barbarian exclusive unit stats weren't listed on the CivFanatics Gods and Kings unit list?

There are two Barbarian exclusive units that I know about: the Brute and the Galley. If I recall correctly, the Brute had the same stats as a Warrior, but the Galley was marginally weaker than the Trireme.

Funnily enough, the brute does have different stats to the warrior. It costs less to manufacture. The only thing I can think of that this affects is upgrade and disbandment costs.

I kinda wish they'd given all the barbarian units different names and stats. Would be cool to see AK-47-toting "rebel" units in the modern age.
