Not until way after 1.0 -- permanently. We removed it not because we ran out of time, but because the concept and presentation was confusing and bad. The core desire to have base building is good, and after 1.0 we want to do more of that, but sticking it in a tertiary interface like citybuilding was is a mistake I won't make again. It's either on the world map or the side view areas that it needs to be.
