The EB Team is not CA, they are highly specialized, which is part of why EB is so splendid. Most of the EB historians (and all of the historians in general for that matter) have exceedingly in-depth knowledge about one specific time period and location, knowing much less about other periods/places. In order to move on to a "different time", much of the EB Team will have to quit and new recruits will have to be found. Its tough. Of course, my wishes are the same as yours, I want a different EB as well - I love Asia ton Barbaron and I wish it was the successor of EB I, but alas, not everything happens according to our wishes...

Bronze Age EB would also be nice, but only after AtB.
