It's looking like Update 2.3 is heading to be a biggie in terms of content
Daglar more or less confirmed a new Chronicle was coming in 2.3 and is the first of many more...
More chronicles are in the works. You should expect one with 2.3.
Still no sign of it on PTS yet, hopefully they'll start to add 2.3 'goodies' onto the PTS by this weekend?
So far it seems:
New zone: the Dendrome
New Expert/Master Mode Dungeon: Realm of Twisted Dreams
New feature in Dendrome: Strongholds
New Chronicle: nothing known yet
Soon as i know, you'll know, time to camp out the PTS
Edit, another cryptic post by Daglar "suggests" that we might be getting more Role slots in 2.3
