I must be one of the only people who doesn't want samurai as the next job just because it'd look far too much like a dark knight (especially with the current doman gear) and--depending on what role it would come in as--play too much like a job we already have in this game.

I do agree that the next job should be a DoM. The only real issue with this though is that the top candidates for this (red mage and blue mage) are traditionally hybrids, which would be a lot harder to fit into a game where it's one role to one job.
