Yes, according to the description it should work as the culture bomb does now.
edit: And it keeps it current abilities.
Makes sense that the Citadel deals -3HP (-30HP in GaK) to adjacent enemy units in your territory, so it logically expands this territory. Nice.
But they NEED to give Great Artists a new ability. Maybe contributing a lot of culture to Social Policies? Like in Civ 4, Great Artists generated a couple thousand culture points.
