This page shows, Diablo, the female demon hunter, and male witch doctor will be included. It also shows their actual names, Valla and !@#$ba respectively.
Valla was the name used the pre-release demon hunter short, right? Have we ever heard %^-*ba before?
I don't read any of the books (mostly just the lore on the wiki), so this might just be an obvious I'm late catching up on.
EDIT: For some reason the WD name keeps getting edited?
EDIT 2: Haha. Figured it out. The first half the name is getting edited.
