A'ight, since this has already been revived I'll post this. Yoshida did another interview with Famitsu, of note:

Regarding the main story:
With Nidhogg's roar still being effective, the dragonsong war is not truly over and this will be the focus in the following patches.
In the following patch 3.x series, the reason why Asciens exist and what the WoD trully is will be revealed. 4.0's flow will move towards a different route.(Asciens and Dark existences will still be there as a back bone but it will be an independant story just like heavensward )
