In his response, he didn't talk much about why Samurai wouldn't be hard to do, so it's a possibility that it could be the next job. However, I'm thinking it won't be because he said it would be surprising to the players. Blue mage and Red mage seem to be ruled out. Now it's time for everyone's speculation......notice the use of the word time.....Time Mage confirmed along with Half-Life 3.
