So far, most of the group dungeon quests have been given veteran quests for follow up and closure for their respective stories. However, some quests are still left hanging. For Selene's Web the rogue mage Warlock Carindon had enslaved Selene's soul. So the next part would be do defeat him and free her. In Volenfell, an undead army was released with the removal of the Guardian's Eye. So the next step would be to put the Eye back and stop the undead army. Finally, in the Vaults of Madness, Gasteau Chamrond declared that he would replace the Mad Architect. So the next quest would be to stop him. So far I've heard no mention of a release date for veteran versions of these dungeons, let alone if they are planning to develop them. If someone could give any information on this I would appreciate it.
