Going back to look at Letter XVI, I noticed under the 1.19 list that a new low level public dungeon was to be added, but what exactly does this entail? I'm guessing a public dungeon = something like Cass. hallow, one of the mines in Thanalan, or Tam-Tara deepcroft, but would it be a brand new area altogether, or simply one of the areas that are currently locked off via an NPC guard?

Usually with something like a new dungeon being added, we'd have seen a preview by now...unless they want it to be something of a surprise.
