...will it be present in DoF? If so, will it be set from the start or will it increase/need to be upgraded during the game (maybe by upgrading strongholds). Will it be the same for all races (maybe Orcs require a larger pop cap since they'll probably be going for "mass effect"). Will dragons have a separate pop cap for their "conventional" units and the Dragons themselves, similar to how in Universe at War Hierarchy has two pop caps for units and walkers? Will mounts maybe have a pop cap of their own? Maybe some other special units? K, that's it I think.
