Hiya mate! 
Well the thing of it is this. If I use two arms (in 3E) for wielding a weapon I get x1.5 my strength bonus. So you one armed strength is a subdivision of your full strength.
The question then becomes do I get more strength for additional arms or do I still have the same total strength lessened for each arm. I favour the latter idea.
If you take a Hekatonchiere and a Titan (3.5). They are both the same size, but the Titan's arms are far more massive. If anything the Hekatonchiere has medium sized arms and the Titan has Huge arms.
4th Edition neatly solves this by giving an average damage for monsters of a certain level. Then dividing the damage up between attacks. So it will be interesting to see the difference in damage output between the 4E Balor and 4E Marilith. Although I am sure the Marilith will have some interesting opportunity attacks.

Kerrick said:You're forgetting the Golden Ratio. A 4-foot-tall human would have an upper body roughly 2 feet tall, which is nowhere near long enough for six arms. Unless you meant the torso is 4 ft. tall?
Having Medium arms makes more sense all around, but having two different Strength ratings (one overall and one for the arms) is just odd. Give it an overall Strength of 18-20; it's at the upper range for Medium creatures, but the marilith has a lot of mass behind those arms, despite the fact they're smaller than normal for its size.
