Considering that the current MSQ looks to be arcing from ending the dragonsong war before 4.0 and then doing a backstep (related to known storyline) and having us go and liberate Ala Mingo (and about MFing time considering how much we have heard about it in 2.0 and even 3.0 to date):

Are there any plans or conversations happening that will open up Iydlshire and The Hinderlands through a side story quest?

Between the Goblins, Scions, and even the a particular batty old lady (and her brooms considering they are really talkative), there exists quite a bit of points for shoot off.
