I expect (actually, expect is too demanding. Say, rather, that I hope for):

- More roleplaying opportunities. Charisma attribute would be nice, and so is a diplomacy skill.
- Better character creation that allows for more individuality. At least give me different races to choose from.
- Acknowledgement of different genders. In DD, the only place being male or female matters is the inane elven romantic interest.
- Different factions and lots of intrigues, or at least different ways to do quests. See Lionheart.
- Bigger world, longer game.
