There is no Screaming, Because we know they are coming.
Mission Accomplished

There is nothing to show because they are in Development. Just like Male Viera we likely wont see or hear about it till the the end of the Expansion and they start to show off and Promote the Next Expansion.
They decided to do 1 at a time instead of Both so they can give them the proper attention.
I personally hope that the extra time being put into the FemHroths will be worth it, and by extension will improve the MaleHroths
