Creating 20 quests in 2,5 years is too hard for them.
Oh the hardship of a small company like Square-Enix...

How could they possibly make quests for an expansion, there surely won't be any new quest in DawnTrail.
We'll, of course get the bare minimum, like a catboy eating a HD taco, THAT is necessary for the immersion and fantasy !
We can't have them waste time on a few lines of dialogs for preexisting stories, cut-scenes of people talking -moving even- or a fight against an already existing generic enemy.
