I envision something more along the lines of Rome:Total War or Battle for Middle Earth II, actually. Only difference is that you can create and disband your battalions at-will. And if you batch train 20+ units, they will come out as a battalion. BfME2's battalions were very easy to use. The problem with R&F's "battalions" is that they didn't act like coherent units. This is nothing like how I want 0 A.D.'s battalions to behave. The ease of pathfinding and control from BfME2, with the formation cohesiveness and tactics of Rome:Total War, plus our own little touches, is how I envision them working.(another thing I love about BfME2 is its wall system--it's nearly perfect if you ask me, but that's a different discussion)
