Imperial Centurion -

http://k.min.us/jkw9oW.png (has what looks like a 3 pronged tail, not the wolf/jackal model)
http://k.min.us/jkwYO2.png (never seen one look this monstrous)
http://k.min.us/jkw9oU.png (looks similar to XI)
Also it seems like all the beast tribes have specific class names like XI...not sure if they were there before, or just general race names. There are even a few seemingly NM names for Goblin, Kobold, Amal'jaa and Ixali tribes.
