New Public Dungeon to be added in 1.19?

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.

It's prob the ant nests
Edit: I take that back, the new dungeon was supposed to be for low levels.

No idea tbh.

Yoshida talked about a noob dungeon in the March interviews. A place where the improved tutorial takes you and makes you group with other noobs. Since it's called a public dungeon I dunno if its different from the existing dungeons, but- I think it will have some similar mechanics as the beastmen fort raids....as in, the monster #s are scaled to fit with the number of players inside. Maybe something else too.

In a nutshell, it's probably a low level beastmen fort-style experience for tutorial purposes.

Well there are these too:

Enemy distribution adjustments
Redistribution of enemies in six areas
1.19 will focus on lower level enemies in six areas.

Design and release of notorious monsters
Addition of new NMs for low level dungeons
Adventurers may come face to face with a certain feline monster that starts with C and ends with OUERL.

While redistribution might not be a factor with the new dungeon, the Couerl might be...so I cant really see them throwing that at new people in a tutorial low level dungeon. Of course an actual dungeon that works as a tutorial would be nice though.
