They did make an announcement on the forums:

"Hi Summoners!

I was informed of this new dungeon in the Vortex and I'm already doing further research for it. I'm also interested in getting more information for Xie'Jing. If I will be able to collect enough data for Xie'Jing, I might be able to create a mock unit of her and test on you again. Are you up for this challenge? Let me know of your thoughts about it.

Noel"
