Is ninja confirmed the only new job?

New tank class to be released, in my opinion, will be Samurai. In a toss up between making Dark Knight or Samurai a DPS, Dark Knights have historically followed the "Inflict self-damage for more damage output." with the exception of FF11's DK. (Correct me if I'm wrong?)
