We'll be removing them as they exist today (Wonders). They will show up in a province's list of existing buildings, and on the battle map, and there will be more of them. However, their effects will be drastically reduced, and unfortunately they will not show up as separate on the campaign map.

We consider this a good tradeoff. Removing some eye candy from the campaign map (only) for much less imbalancing effects, more in line with what they might have actually provided to a province (a small bonus to morale, or law, or what have you) rather than a huge faction-wide bonus. Plus we're adding some of our own creation, and as soon as Verci and Ailill crack the building code we'll add more to the city plans as well.
