I also remember OWI saying that for Hand of Odd, you would be able to download new content to keep the game fresh. New areas, new npcs, new units, etc. So the game would always have some new aspect for you to go off and see, or explore.
I think later in the Quintology, they could do a coop feature like the ROTK game for online. Where five friends could play together and each take one of the main heroes, etc.
