One of the things about the beta is, it can still surprise you. CM Zorbrix just posted to the forums about something we've all been wondering about - several of the new character models will be making their appearance in the beta. Both male and female trolls, human males, tauren females and night elf males will all be playable.
It's important to note that the night elf male hasn't even had an Artcraft yet. This is definitely a work in progress, as was the case when the draenei male appeared on servers before it was previewed. But I find this amazingly exciting - finally we'll get to see how these models look in action.
We've added a slideshow of the new night elf male model below for players to look at.
