Well okayt, but Bethesda doesn't seem to be good at making epic battles, maybe in the next game they can make epic battles with thousands of soldiers on the Battlefield.
That isn't going to come around for a long time. Not with the current game mechanics that the Elder Scrolls series deals with (its already possible with something like the Total War series, but that is a completely different game-genre and thus has different inner workings).
So with that in mind, I say no to any attempt to portray a large-scale war in-game. Its just not feasible and would leave us all disappointed.
