It does. They have added new factions that I had forgotten whether they even existed or not!
From what I hear they are doing a great job on the custom settlements; the Tower of Orthanc is already done and they are looking at making the Black Gates next. They are even apparently thinking about adding a thingy that toggles whether the Black Gate is open or closed both on the campaign and battle map which just sounds really cool.
