I would like to see a separate adventure/module. Shadowrun Dragonfall taught me how much fun a 15-20 hour RPG can be, so it does not have to be as long as the main game or get you to level 20. Matter of fact it would be more fun to start at level 5 so you feel less powerless.

I would also like to see the Oracle, Witch and Summoner as well as the Hybrid classes :)
