Considering that the base RTW has a single campaign/period, BI has a lot of ground to make up. And the problems with RTW run deeper as well. This looks more like the missing half or RTW than an expansion pack to me. VI had a completely new campaign map and campaign in addition to its updates of other three campaigns on the normal map.

I have to agree with others that the barbarian invasion phase historically is less interesting to me than Alexander, etc.
