IDK but i think is just an excuse to sell the game again....Oblivion had big DLC's and were sold via DLC or expansion disk. Don't get me wrong , i love D2 and i'll buy the new version ; but i really feel i am getting cheated when the devs say that the expansion is so big that we need to do it that way. Why no sold it like a sequel if is so big or like an episode. I hope the graphic don't be blurry like in the first DV2 to make worthy re-buy DV 2 again.
Actually I could tell just from Ego Draconis itself that the developers intended there to be more content in the game, but they didn't have time or the budget to put it in. Aleroth is a huge city which you can explore only a tiny part of and do only one quest - the main quest.
There's also the case that for a game which hypes up becoming a dragon and getting a battle tower. you spend more time earthbound without a tower. That also suggests that the dragon with tower part of the game was intended to be longer.
I also note that many of the mini-movies show fighting in the streets of Aleroth, which isn't in the game.
