Will there be any expansions for Heroes 5?

Where would we be without expansions? They were present in all parts of the Heroes series, and they will be in the fifth installment as well. It is highly likely that they will add 2-3 new towns (I would like to see dwarves in the style of Disciples and Atlantis with monsters from Greek mythology), several new guarded treasure locations on the map, a dozen or so artifacts, and, most importantly, a RANDOM MAP EDITOR.
