I am trying to figure out whether Bethesda will include mounted combat in the next game or not; and seeing as it would change the gameplay dramatically, it seems to me that it could be largely dependant on the province the game is set in. Cyrodiil sounds to me like it should have been a perfect province for it: as the capital province, they would need horses to travel quickly to areas of unrest, and yet mounted combat not put in. Nordic culture sounds to me like it would be more infantry-based than cavalry-based, (though what this is based on I don't know), so, the question is: is cavalry a major part of Skyrim armies, etc?
I have a bad feeling that I have forgotten about some obvious in game book that deals with this...
