Maybe. There isn't any content outside of M+/Raid to do this time around, which hasn't been true in the past (see AP, islands, torghast, rep grinds). They also said they want to do more frequent smaller patches. This would lead one to believe they're going to drop some kind of story quests every couple of months. Unclear that the incentive to do them would be if they aren't tied to player power.
