We’re shown the fancy UI which lets us customise our NPC brothers in arms, and are given a glimpse at the Enchantress, the Scoundrel and the Templar.
It’s unclear if we could have one than one of these followers aid us out in the field, like was originally shown nearer Diablo III’s unveiling, or if Blizzard have changed the system to restrict us to just one. At least we can tweak their looks anyhow.
Diablo III still carries no firm release date - it simply ‘will be’ one day.
