When will next Episode Air?

I saw the, Nero, Constantine, and Fall of Rome episodes only, and I liked them quite a bit. This series is nothing like them though, as those were like tiny movies with spoken dialog by the actors.

This more like the recent show "The Revolution" that was on history a few months back. It has a main Narrator, and various experts on the subject discussing the people and events that were occurring, while you see re-enactments and detailed maps of troop movements, and battle locations. You never actually hear the re-enactment actors say a word. Very well produced though.
