For another theory that didn't come true in EW but I feel will still happen somehow - I was convinced that the quest chain involving finding that one Garlean boy's parents that established his mother worked as a maid for Nerva's branch of the royal family and that they were hiding out at Palatium Novum meant that one of the optional 80 dungeons would be a crawl through another ruined Garlean manor/state building to be an aesthetic version of Tower of Zot without the Giger tower additions - the Academia Anyder to Amaurot dungeon of ShB. I think predict one of the patch dungeons will be 'domestic' Garlean, if it's 61 or 6.2.
